Oracle form builder 10g is not opening any form ,on Vista

Question

I have installed DevSuite 10g and its update in my Vista machine. Everything is working fine ,but when I try to open any form in form designer(form builder) the form builder crashes and it gives me error saying-
"Oracle form designer has stopped working
A problem caused the priogram to stop working correctly. Windows will close the program and notify you if a solution is available."
It does not get any problem if I try to open any other file. But it crashes when try to open any fmb file. Please help how can we resolve this issue.

Answer 1

Please try this and report back:
In your Vista platform, create a simple form. No canvas required, just two procedures:
PROCEDURE P2 IS
BEGIN
NULL;
END;
and
PROCEDURE P1 IS
BEGIN
P2;
END;
First, create procedure P2 and compile it.
Then create procedure P1 and compile it.
Go back to P2, and remove the semicolon after the NULL. If you try to compile it, it will fail.
Go to procedure P1 and try compiling it.
Does Forms Builder crash at this point?
