After logging in I keep getting the following warning: (As my sysytem is in Dutch, I'm translating the text):
"An unfinished (unprocessed) exception has occured in the application. If you click on continue, this error will be ignored and the application will continue further. If you press on close, the application will be immediately closed.
Unable to reverse the balloon to position '(X=1146. Y=778). The point is not within the visible boundaries of the screen.
Name: Point
Real value was (X=1146. Y=778)"

In my system 'Microsoft.NET Framework 3.5 SP1' is installed.
Why do I keep getting the above mentioned warning? Can somebody help please.

You've installed an application which appears to be crashing. If you check the Event Viewer (run EVENTVWR), there may be additional information in the application or system event logs.
