[Gambas-bugtracker] Bug #2266: Datechooser stalls application

[bugtracker at gambaswiki.org]

http://gambaswiki.org/bugtracker/edit?object=BUG.2266&from=L21haW4-

Anthony TEKATCH reported a new bug.

Summary
-------

Datechooser stalls application

Type             : Bug
Priority         : High
Gambas version   : 3.16
Product          : QT4 component


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

The DateChooser, and other Chooser components stall the application when shown.

I have reproduced that by putting the DateChooser and a Button on a new blank form and trying to run the application. The button will not show up if there is a DateChooser on that form.
