I am using Visual FoxPro 6, Service Pack 3.

I create 1 instance of a modal form using command:
obj_form = NEWOBJECT(class, classlib)

This works fine.
When I am done, I release the variable obj_form to remove the form from memory.

When I try to create the form a second time using the exact same command, I get the error message:

'PARENT' is not an array

I am modifying code in the SBT (now ACCPAC) Pro 6 Accounting system.
