[RESOLVED] [1.0/1.1] System.Runtime.InteropServices.SEHException

[Fishcake]

My clients IT department suddenly and without warning upgraded all their machines to Windows XP from Windows 2000.

This has stopped the application we have written for them working after over a year of (relatively) trouble free use.

The error is occurring whenever a dialog window is closed. (stack trace below)

My development environment is also Windows XP and I have no problems.

Any ideas?

Trying to use manifest file instead of enablevisualstyles, hopefully this will resolve it.

That did it.

This might be of some help. But apart from that i suppose you could try catching the error if you haven't already.

Thanks, I did come across that page but I didn't like the idea of the timer hack. Using a manifest file is the cleanest and quickest method I came across.
