Re: [paragui-users] a little more info to help -> maybe not a dll problem

Hehe,...

You are creating a static object (PG_Button) inside a function and
insert it into the list. The function returns the object gets deleted,
the list accesses the deleted button ,... bang.

Usually the compiler complains about this (at least GCC) with "taking
address of a temporary".

Create the button dynamically (new PG_Button) and everything should be
fine.
