Tony MOREHEN reported a new bug.

Summary
-------

Under gtk3, Gambas's ProcedureList button fails

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


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

btnProc on FEditor is a menubutton.  It is the Procedure list button visible when you are entering code.  When gambas is run under gtk3, it will work properly for a short time (maybe only once).  After that, when you click on that button, the list of procedures does not drop down, gambas is no longer the active window and the btnUseInheritance button on FMain becomes selected.  Gambas under QT5 seems fine.
