Summary
-------

Designer behind toolbar stops toolbar working

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Development Environment


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

I have been experiencing a problem for some time that was only occasional.

The problem was either the "Menu editor" button or the button that goes from form designer to code editor will not work. (probably others but definitely those 2)  they just do not click.
My solution has always been to reload the project but i have just discovered what is doing it.

If my form designer height is larger than the ide window so i scroll down.
if the form contents have scrolled up behind the toolbar buttons then they stop working.
if i scroll to the top of the form bringing everything down then the toolbar works again.
