Long time ago i have noticed that whenever i click a menu in my xbase ++ customized program i always see the same menu item re-appear again in split seconds near the oroginal menu item screen location.
At 1st i thought it was some defect in the xbase ++ compiled program but today the same thing happened with my editor MED CX when i try to paste a string with the context menu.
As a result, i google for more info and have found a youtube with the link below

It is the 'Fade out menu items after clicking' in the Performance Options->Vusual Effects that has caused the problem.
Below is the step to uncheck the option
1. Right click "My Computer: and click "Properties"
2. Click "Advanced System Settings"
3. Under "Peformance" click "Settings" you should see that option.
Uncheck the option and click 'Apply'. Thats it.
P/s: Windows 10 doesn't quite affected by this issue.
