Re: Forms 4.5 Excessive Stacking

Unfortunately, in Forms 5.0 on Win95 if you will use many CALL_FORM in your application, then your application will crush :(

It will be work slowly and slowly... (disk i/o grow and grow)... and crush (application).

Can somebody find any solution? Any help would be greatly appreciated.
