Bug on iw15.2 - invalid pointer and av

[joelcc]

I loaded source for iw15.2.12 and tried to debug the issues but could not get 

I found that when the program creates a form from scratch everything works but when I try to go back to reshow the form (after I have been to another form) then it gets the AV, etc.

For now I had to roll back to iw15.1.22
