Colleague of mine spent most of yesterday trying to work out why any message boxes that our .net applications popped up contained invisible text. The box grew when more text was added so we knew the captions were there but they just couldn’t be seen. A quick test exe confirmed that it was only a problem on his machine (elimimating the build) and a quick VB6 app worked fine on his machine (so it had to be a problem between .net and the win32 api).
Eventually he tracked down a note on the internet somewhere that pointed him to McAfee being the culprit - when he turned off ‘buffer overflow protection’ all the pretty captions came back. Not before he has reinstalled the framework though.
