Can't use tools anymore on Snow Leopard 10.6.5

[noippe]

Hi.

Since a while I cannot use gimp tools on images anymore.
It is not possible to use any of the tools of the toolbox.
When I select a tool (either from menu or from toolbox), I get the tool (e.g. rectangular selection, or brush, or whatever else) as mouse pointer, but when I click and drag on the image, nothing happens.
Also the context menu doesn't open when right clicking on an image.

Other image manipulations, such as rotating, coloring or applying filters are working without problems.

I've gimp for Mac 2.6.11. I removed an reinstalled gimp, problem still exists.
On an other Mac the same gimp version works without problems.

Has anyone an idea what could be the reason for this strange behaviour ?

I have seen this before, and sometimes its just that your image is not the active one... or something like that... i dont remember the details... but i think there is a drop down menu you have to select your image on....

I found the reason for this strange behaviour.

The reason were wrong settings for the input device (I once played around with a graphic tablet, I believe that was the cause)
After setting the input device back to default settings, everything works fine.

The settings can be found under (german version):

Bearbeiten --> Einstellungen --> Eingabegeräte
Gerätestatus jetzt auf Standardwerte setzen

In the international version I suppose it can be found under:

Edit --> Settings --> Input Devices
Set Device to default values
(or similar)

Cheers,
René

As an addition to the above post, I'd like to point out that apparently the Mac version of Gimp cannot handle two input devices at the same time (as in, Tablet and Mouse). Activating one deactivates the other. That's just the way it is, and lisanet has specifically pointed out that it's a flaw in X11/XQuartz.
