Comment 24 for bug 1400234

If you are using trunk version you might want to deactivate spacebar panning entirely (middleclick panning still works): in preferences->behavior->scrolling, uncheck "mouse move pans when spacebar is pressed".

We (or at least I) still have no idea what is wrong with that particular keyboard, and when i contacted logitech support with the bug description, i got the following reply :

"There's nothing special on the keyboard, it's just a generic keyboard. The device doesn't require any drivers or software, other than the default device drivers built into your operating system. Once the keyboard plug in to a USB port on computer, and the drivers will install automatically.", which was not that helpful...

I don't own a k120/k200 myself, but if you have any idea how to troubleshoot that, please share.
