Claus DIETRICH reported a new bug.

Summary
-------

Unintended Redo in the context Menu of the TextArea

Type             : Bug
Priority         : Medium
Gambas version   : 3.18
Product          : Unknown


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

Under certain conditions the TextArea shows an unwanted behavior, which can be reproduced reliably (also see attached screen video):
1. Put some text in a TextArea and replace it through copy/paste
2. Now try to repeat this as follows:
Mark the entire text in TextArea again, press the right mouse button and keep it pressed. Move the mouse cursor so that the most upper context menu item "redo" is highlighted and then release the right mouse button. In this moment the former text appears in the TextArea.

With this behavior the the TextArea it sometimes happened unintentionally, that when I want to paste a text into the TextArea with the right mouse button (and the context menu), that the former text appeared (=redo) and the context menu disappears. This can easily happen when the mouse cursor slips a little to the right before releasing the right mouse button.

The context menu items should only react if the left mouse button has been pressed. 

I hope that this can be fixed. 

Best regards
Claus
