Summary
-------

Bug on modal persistent dialogs with Qt5

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : QT5 component


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

I have a problem only on Qt5 when open -> close -> Open a new time   a persistent dialog... It look like a freezing.

I've seen than in the IDE on the option dial and project property dialog too. At the second opening the windows take time to open and the content is not diplayed.
