I have a very simple block of code with open a file in a thread
and for the life of me I have no idea, wonder if it's a 2.0 beta bug?

here is my sample (which open a file in a thread)
=3D=3D=3D
public void Open(string file)
{
Cursor =3D Cursors.WaitCursor;
new Thread(delegate()=20
{
RecipeFile rf =3D null;
try
{
rf =3D new RecipeFile(file, false, SetStatus);// is =
ThreadSafe, only independant data
SetStatus(strings.done); // is ThreadSafe
}
catch (ArgumentException e)
{
SetStatus(e.Message);// is ThreadSafe
}
catch (SQLiteException e)
{
SetStatus(e.Message);// is ThreadSafe
}
finally
{
// error happened here in GUI thread: Cursor =3D =
Cursors.Default; =3D>AccessViolationException
this.BeginInvoke(new InvokeDelegate(delegate() { this.Cursor =
=3D Cursors.Default; }));
}
if (IsDisposed)
return;
this.BeginInvoke(new InvokeDelegate(delegate() { RecipeFile =3D =
rf; }));
}
).Start();
}
=3D=3D=3D=3D

If you're in a war, instead of throwing a hand grenade at the enemy, =
throw one of those small pumpkins. Maybe it'll make everyone think how =
stupid war is, and while they are thinking, you can throw a real grenade =
at them.
