strange response from FS with new gauge

Hey all, Well, I thought I had my first gauge about done, but I've run into something very werid, the gauge was created in Visual C++ 6.0 Pro, seems to build ok, the debugger doesn't flag anything when I create a debug build, but when I go to select the aircraft in which to test the gauge, FS crashs to my desktop at the aircraft select screen after I press Ok. I've looked over my gauge code, the entry in the panel.cfg and don't see anything wrong, I'm at a lose of words as to why FS crashs like this, any suggestions be appericated. Jared
