Black flicker at start and end of Thumbs Plus

Windows 7, x64, Thumbs PLus 8.0.3516
When starting Thumbs Plus the screens become black for about 1 sec and Windows issues the message The color scheme has been changed to Windows 7 Basic
When terminating Thumbs Plus the screen again flickers black (about 3 sec after clicking the X button).

Settings in TH+:
Windows > Themes > Standard (unfortunateley no check mark is applied to the selection, so it is not known whether this is persistant or not)

Program propterties of Thumbs8.exe:
- Run this program in comaptibilty mode for Windows XP, SP3
- Disable visual themes
However, none of these settingns has any effect on the reported behaviour.

How to get rid of this harassment?
Is it possible to set a flag in Windows to avoid such behaviour?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Must be due to how windows 7 uses direct draw to view certain images / video that do not meet the Aero standards, possibly the 64 bit is showing some incompatibility remember this is an advanced os.

Run this program in comaptibilty mode for Windows XP, SP3< maybe this wont apply since it's a 64 bit

ThumbsPlus version 7 includes new toolbar buttons and graphics with a Windows XP feel, improved menus, and a much wider selection of buttons to choose from.
Try the latest version and check if it runs on 64.

This is an excellent solution, Merete

I have downloaded version 7 SP2. I is (same as version 8) a 32-bit programm (as Task Mgr states).
And: [i]it does not flicker.[/i]
I had switched to version 8 only to be shure to get a W7-x64 version, but version 7 SP2 of Thumbs+ is OK for me, although there will be no further updates possible.
In a word: problem solved
Thankyou kdaube you are most welcome  :)
All the best
