Forms6i run-time crahses as I change pll

Question

I am sharing some data between forms (6i) using pll. Variables are declared in a package spec inside pll.
As soon as I change the package spec (to add a new varibale, all the forms start to crash).
The only way to resolve it to recomiple all the forms (which are referring to these pll variables). Sometimes I had to put some messages in all program units for form to work (as it seems even copile all doesn't compile it)
Why is it? Is there a bug in forms6i
I though changing pll should requires recompiling all forms!
Please help.

That's the problem with Forms storing old compiled code inside the fmb.
Clean out all the old compiled code using the semicolon - semicolon replace all, then save the fmb, then close it. Then open it, compile, and close again withOUT saving.
We go to great lengths here to keep the PLL libraries UNcompiled, too. It keeps the source code files (.pll and .fmb) much smaller.
Here are the links explaining the fmb size issue and the semicolon replace procedure:
