The error happens in the MinHook hooking library which the tweaker uses, and error code 9 is MH_ERROR_MEMORY_ALLOC, which means that the library could not allocate the required amount of memory. Could a limited amount of system memory be the issue here? Also, are you using a 32 or a 64-bit system?

You're right. Seems like it's not new. I'll look at it.

No problem, it's not something a screenshot cannot fix :)

OK, I believe that I could reproduce it, and probably fixed it.
Please try the following version:
https://www.dropbox.com/s/64c32kbcw75hzvw/7tt_setup_beta_v4.5.6.4.exe?dl=1

Unfortunately, I could not reproduce it.
If you'll be able to come up with exact reproduction steps, please let me know.

Here's a debug version:
https://www.dropbox.com/s/oyth5yaqzv4rlnz/7tt_setup_debug_v4.5.6.3.exe?dl=1

When run, it should create a file with the name _DEBUG.LOG on the desktop. Please reproduce the error, and post the contents of this file. Thanks.

OK, so you're talking about the Taskbar Inspector. The 7TT (or 7+ Taskbar Tweaker) window is this.
I'll try to reproduce it.

7tt has a vertical scrollbar

Are you talking about the taskbar? 7TT does not have a scrollbar.

All in all, I'm not sure I understand your issue. Could you please provide a screenshot?

Are you getting the same error number (206)?
That doesn't seem to correspond to your crash log, but it's difficult to say for sure.

I've installed Chrome on Windows 7, and made a clean reinstall of 7+ Taskbar Twekaer, with no settings turned on. Unfortunately, I could not reproduce the issue. Does it also happen with IE on your PC?
