Hello:
I have loaded the mdi editor example in version 3.7. If I right-click (double) on the frmDocument, Firefly shuts down. This is repeatable on a brand new (spanking, even) install. I get the little dialog that says windows will close the program and notify you if a solution is available. I am hoping that you are quicker than those guys. I hope you don't have to wait for your computer to thaw out in the spring because when that Canada air gets to Louisiana, it is still too darn cold. Oh yeah, I almost forgot, the project compiles and runs normally if I don't irritate it with the right-click as mentioned above.
