I've got a strange problem... hopefully someone here will know more about this than I do.
I have 2 programs, A and B. A will sometimes need to call B and when B exits it needs to return control to A. They call each other via SysUIAppSwitch. When A calls B, all goes well, however when I try to switch back from B to A I get a Fatal Alert saying it couldn't find form shadow for window. The really weird thing, though, is that if right before B calls SysUIAppSwitch I do a FrmCustomAlert so I know it's about to switch then A relaunches perfectly.
I'm guessing then that A has trouble redrawing its form when it's relaunched (although I don't know why it would since it acts as though it were a normal launch) or that B has trouble exiting. I don't understand why the FrmCustomAlert would be affecting things, nor do I know what it would be affecting.
Are both application A and B calling FrmCloseAllForms as part of their shutdown code? Do both applications correctly call FrmDrawForm before trying to call any routines that might redraw items on their forms?
