Okay, .NET geniuses, here's the relevant part of my code:

    adapter.Fill(table);

    return;
}
catch(Exception ex)
{
    SqlException sqlEx = ex as SqlException;

I have an exception that's being thrown by adapter.Fill(), and when I put a breakpoint on the first line in the exception handler, the Exception.Data property already contains a key that is unique to my application.

The thing is that it does not happen every time, but only when this exception is thrown within ~2 seconds of it last being thrown.

Explain that!! :)

Thanks!
