[Gambas-bugtracker] Bug #2547: Application.Main = Me causes window stacking problem

[bugtracker at gambaswiki.org]

http://gambaswiki.org/bugtracker/edit?object=BUG.2547&from=L21haW4-

Christof THALHOFER reported a new bug.

Summary
-------

Application.Main = Me causes window stacking problem

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Unknown


Description
-----------

If a main form of an application contains the code "Application.Main = Me" in '_New()' the windows stacking is disturbed. When from this main window a second window is opened from which a third one is opened the main window moves upward in the stack just behind the third and over the second.

I attach a project that shows what I mean.
