Here is the environment information you asked about:
| Working Machine Non-working Machine
|O/S 2003 Standard 2003 Enterprise
|Hardware Virtual Virtual
|Mem 2GB 4GB
|Citrix Using Terminal Server Using Terminal Server
|Drivers Up to date Up to date
|Software Up to date Up to date
|DirectX 10 No No
I should be noted that we also have a non-working 2003 Standard installation, but it was not used for this testing to isolate the issue. We are looking at all hardware and software to narrow down the root cause of this issue.
I created a Winform App with a RadMenu and place 4 Root entries.
This application shows the in blue originally, and highlights to yellow, but on one machine the menu stays highlighted, but on the other it does not.
I then added the line:
Me.RadMenu1.Behavior.BitmapRepository.DisableBitmapCache = True
And still had the same results.
I could not seem to find anything under ThemeResolutionService for AllowAnimations, and could not find anything when searching your sight, so if you could provide a little more help with this setting, I would be happy to test it.
I could not find anything on SuspendAnimations, but I did try the DropdownAnimationEnable, and tried changing the Frames and Easing too, but always got the same end result however adding frames just made it take longer to display.
If there is something else you would like me to try let me know.
