I do know that mabry controls ARE NOT tested in VFP. I used their SocketX COM Component with no problems. Which one are you using???

>>I seem to recall an issue with C5 when you toggle the visibility of the main VFP screen. Just for grins, don't set the Visible Property of the screen to .F., and let me know if you still get the C5.
