I just tried to run a simple VB.NET 1.1 winform on Mono 1.1.14Build1 and got the following crash (see below).
The reason for this simple test was to see if Mono leaked memory like MS .NET 1.1.
If you run this on Windows, click the button over and over and over again..
And watch memory. It grows in memory... The test was to see if Mono did the same, but it crashed before I could check.
So a couple of questions..
1) Why is it crashing on Mono
2) Is this a Memory Leak ? or Incorrect coding for Simple Threading ?
Thanks
Andrew
