Unhandled exception Ultrawintoolbar
posted

Hi,

We're using Infragistics version 10.3.  Some of our users have been complaining about the UltraWinToolbars freezing when they try to hover over it.  Our application is run using the Application.Run() and in the event handler Application_ThreadException

Application.ThreadException += Application_ThreadException

We get the following stacktrace:

Misc - 2019/06/11 09:38:27:724 - Cat:0 - [Thread 1] An unhandled exception was encountered and Application_ThreadException invoked: : - The operation completed successfully

I've read from other posts that as it begins with a NativeWindow.callback it might be an issue with thread marshaling or that it might be due to a lock screen on window 8. 

https://stackoverflow.com/questions/16435213/win32exception-caught-by-application-threadexception-missing-own-code

however our users use windows 7 so don't suspect its to do with lock screen. 

Please could you help out here?
