Okay I've been noticing this for almost as long as I've used the application and I'm (finally) starting to realize it's probably a bug and that therefore I should report it. Basically, you know the option "left click on combined item"? Well I normally have that set to "cycle through windows", and while I'm fine with that making it slightly harder to get the thumbnail preview (the default behavior for this action), I have since begun to notice that it also seems to make it harder for me to get the thumbnail preview to open when I'm hovering over an application's icon. At least, judging by the fact that if I disable the tweak (that is, I set it to the default behavior of "Open thumbnail preview (default)"), the thumbnail preview becomes available again when I hover over items.
I'm still not positive on the reproduction steps for this, as it seems to happen inconsistently after some period of time or some unknown interaction. Roughly, however, the steps or something like this:

1. be on 7TT V5.10 (that's the version I'm using currently)
2. open the application's main window (the one that has the about button in the lower right)
3. set "Left click on combined item" = "Cycle through windows"
4. after some time (again, this is where I struggle defining the exact cause. It doesn't take too long though, for me.) spent going about your business, switching windows, dragging title bars, and so forth, try getting a window preview to show up on-hover. You may have to click and empty space on the taskbar so that it's "in focus", but even doing that didn't help me when the issue showed up.
5. Switch the setting back to the default
6. notice that window previews are available on-hover again, at least when the taskbar is in focus

See attached screenshot.

Taskbar v5.10.0.6(Beta)

Outlook 365 for Enterprise

If Taskbar is started before Outlook, the audio alert for new messages does not work.  If Taskbar is started after Outlook, it works but eventually stops.  Exiting Taskbar fixes the issue.  

I've been running Taskbar since the 32bit days and have never had this issue until the latest version.

I can't change volume by scrolling near notification area, but only on secondary display. When option changed to scrolling on entire taskbar it works. Also when volume change bar is opened everything works fine.

On secondary screens the seconds are no longer shown. 

Windows version: 20H2

7T version: 5.10

Repo steps:
1. Enable "Drag to Reorder" under Thumbnails
2. Windows option: "Automatically hide the taskbar in desktop mode" enabled
3. Hover over a program such that a thumbnail displays (thumbnail will never actually display)

Result: explorer will crash, causing taskbars to show, hide, crash and repeat until 7t Taskbar Tweaker is killed.
Interesting find: If option is enabled and thumbnail displayed while taskbars are not hidden, explorer will crash as soon as taskbars are hidden.

Not a huge deal for me as I use right click to drag groups 99% of the time; but I finally found the magic combination and thought I'd submit a bug report for you.  Low priority for me.  Willing to provide more info/testing if desired.

On ultrawide monitors, it would be useful if the taksbar item for a window tries to displace with the horizontal matching window position. So for example if the only app open is notepad, and its window is open on the left side of the screen, the icon would be positioned towards that side, but if the user moves the notepad to the far right side of the monitor, the item would displace horizontally along with the window towards that side too. The result would be icons would be _near_ their windows.

Thank you for this awesome software!

Hi there,

I encountered a non-critical bug with 7+ Taskbar Tweaker I wanted to report.

I have icon 'badges' turned on for programs such as Discord, to indicate when I have a new notification etc.  I noticed that whenever I apply new settings with 7+ Taskbar Tweaker, the badge will disappear, though the icon remains the same as before.

If I just close Discord, or whatever program lost its icon's badge, and then re-open, the badge will re-appear. Still, it's a little annoying that every time I change any setting in 7+ Taskbar Tweaker, I have to close and re-open all programs that use icon badges.

I really don't know where to look here and how to narrow the field of search..

I can't find anything regarding terminations in Event Viewer. It just started to shut down several days ago. 

I just may assume 7+tt terminates because of injection to explorer.exe it does (is it?). It terminates together with "process hacker" application which I extensively use too.

My work became really uncomfortable, I almost don't wanna use my PC now without those these two apps.

I've disabled antivirus and other protection features of windows, but nothing changed.

Apps just shut down every 10-20 minutes saying nothing.. 

May be you can recommend something to diagnose this behavior? 

For now, I'll just try to clarify weather time periods it happens are arbitrary or concrete, I've ran out of ideas for now..
