Here is something wierd. I have an old app that hasn't been used for a couple of years. It still runs fine on my PC but when loaded on another PC will start but the mainform is nowhere to be seen. The following code in in my login form and launches the mainform.

sele control
loca for allt(item) = "firstform"
*set step on
if found()
	firstform = allt(value)
*	try
		do form &firstform
*		catch
*			messagebox("Cannot launch " + &firstform, 16)
*		endtry
*	else
*		messagebox("Cannot locate the main form.",16)
endif
thisform.release

The try/catch and the else phrase was added in an attempt to find out if the users pc couldn't find the form. Now here is what's wierd, on MY PC the program works fine without the added code, but with the added code the program starts and runs but the main form is gone. The debugger shows that the mainform.visible has been set to false. Has anyone run into something like this before?

Thanks
