You are not alone. I'm lost too!

As the problem is not in the Gambas code of the editor (I'm 99,9% sure), 
we must look if it can come:
- From the window manager.
- From the distribution.
- From the mouse hardware - i.e. a bas interaction between the GTK+ 
component and the mouse. I think it's the most likely.
- From somewhere else?

When a system is virtual, its harware is emulated. So if the problem 
indirectly comes from the mouse hardware, the bug may never triggered 
inside a VM.
