Could you execute with "mono --debug app.exe" so that you get line numbers as well? And knowing which version of Winforms you're using would also help :) Rolf >_____________________________________________ >From: Maser, Dan >Sent: Wednesday, August 08, 2007 4:39 PM >To: '[email protected]' >Subject: Handle being created when I don't expect > I've got a situation with MDI forms where the behavior is different on MS vs mono, but it's proving difficult to get a simple test project that >reproduces it.
