One of my duties at my job is to enhance and maintain a mature VB.Net windows application used internally by my company. We run 8 computers at the small company that each runs the app with no problems.
Recently we replaced one of the computers with a pretty standard notebook running Win 7 Professional with SP1 and for some reason, it won't display message boxes displayed using the normal MessageBox.Show("Message") method.
The vendor who sold us the computer says it must be the program, and I kind of sympathize with that view, but the fact is we have 8 other computers that all display their message boxes just fine.
Thought I'd post the issue here to see if anyone else has run into this and, if so, did they find a resolution?
I'm going to paint outside the lines a little bit and answer my own question with sort of a non-answer.
We battled that computer for about a week and a half and finally gave up and reinstalled the OS. Problem solved. Not really an answer because we still don't know what was going on or why reinstalling the OS fixed it.
Reinstalling was really an act of frustration/desperation as much as anything else. In the end we were just thankful the problem went away and we could move on. Figured I'd get this off of the unanswered questions list since I'm not really waiting for or expecting an answer at this point.
