[linux] Mouse problems

[theGiallo]

I'm having troubles with Wings, not with a specific tool but with the whole mouse management.

When I'm navigating through menus and I select Tools/MagnetMask and I try to over a submenu option the mouse pointer blinks to the option next to MagnetMask: Snap Image.

I select a face (or something else), RMB and click something, i.e. Move, the mouse blinks to the right of the screen. I click something, i.e. Normal, the mouse pointer disappears and the face goes gradually to minus infinite. LMB and the transformation is aplyed and the mouse appears at the right of the screen.

Also the ctrl and alt keys make the bottom bar disappear and the hotkeys for undo, and similar do not work. Sometimes they work, I do not understand why.

No error is printed in the terminal.

I'm using Debian testing with gnome shell:

Packages:
gnome 1:3.4+7
gnome-shell 3.4.2-6
wings3d 1.4.1-4
erlang-esdl 1.2-2
nvidia-glx 304.64-4
xorg 1:7.7+1
xserver-xorg 1:7.7+1
xorg.conf (I have a double monitor configuration with the master at right)

System info:
Kernel Linux 3.2.0-4-amd64
GNOME 3.4.2

Hardware:
