I have Windows 7 64 bit, running Classic Shell 4.1.0 with a custom start button.
When I start my computer the default Windows 7 start button shows for a second,
then Ulead VideoStudio 10 SE DVD runs a program in the background (uvPL.exe) which causes Windows
to go from Aero to the Basic look and the custom start button is shown for a second or two,
then it goes back to Aero automatically with NO start button showing; and it stays this way!
If I click on the area where the start button should be it reappears and displays correctly thereafter.
Also, when I run Ulead VideoStudio in:
- Compatibility Mode for Win XP SP3
- Disable visual themes
- Disable desktop composition
- Disable display scaling on High DPI settings
- Run as administrator
After I exit VideoStudio it goes from Basic to Aero and the start button disappears; and it
stays this way (until I click on it)!
This does not consistently happen, bug it does most of the time!!
(I checked this with a larger button, it is not behind the taskbar it is just not displayed.)
Maybe this has something to do with my button .png files. Here is one of them:
