Ok, I believe I just emailed video through mail drop.  I did try uninstalling and reinstalling program, no joy.  I hope the video comes through.  It will only show I open program and I can't do 4-6 minute videos so I can't show how suddenly it goes back to what it was before I changed the taskbar using program.  

addendum: Update: I turned off antivirus and still it happened.  so I now think its not the antivirus, as it happened when I shut down antivirus.  I have windows 10 and its a new thing, but not sure how to tweak it to make this work.

I am using Webroot Secure Anywhere.  I don't know how to whitelist, sorry, maybe you can give me steps? I saw something in the log showing it was monitoring this, and I clicked on allow, but its still closing out. 

I tried multiple times and still cant' upload, but essentially, I am saying that I open this software, click on advanced options, get the bigger taskbar font.  and a(a) go out of app and for awhile this change stays in place, then reverts to smaller icons and the program closes.  Or I leave your program open and minimized and  still it closes itself and reverts at some point, maybe seconds or minutes later.  I would like to know steps to open program make changes and SAVE it somewhere in there, then close out and keep it in place.

as you see I open and then have my tweak of bigger icon task bar and then after awhile even though software is open /but minimized, it just reverts and the tweaker software closes, but it might be seconds later or minutes later.

Well I do leave it in the tray, but settings do not stay active, can't afford to turn off my anti virus, to use program.  Maybe some other way to get it to stay in place/ some saving?

I meant I am not logging off computer.  How do I Run it all the time? leave it open in system tray? I have done that, but it shuts off after awhile and my settings go with it. I open it and then do my tweak and leave it in place, then even minimizing the tweaker, and trying to let it stay open does not leave my tweak in place.  So is there a way to do that? I dont know any other way to 'run it all the time'... can you advise?

I must ask is there any way to make it save that setting? I got it set with the bigger icons on bar, which I love.  But I notice it keeps flipping back to smaller ones, not just when I restart but even while I am doing other things.  Please tell me how to save my settings on this? thanks

Thank you so very much, I was able to access by right clicking the main window title bar.  I was not able  to by the tray icon, but now I was able to set my task bar icons to bigger size which is really what I was after.  I appreciate your help very much.  Thanks again.
