Single-clicking on things with 2.6.24 very frequently gives a "double-click". This does not happen with 2.6.23.8. I wonder what broke it? I've grabbed mousedev.c from 2.6.23 and inserted that in place of the updated 2.6.24 source, but no change. So it's not that file.
Mmm.. reverting the entire drivers/hid directory to that from 2.6.23
seems to have fixed the problem, so we now know it's in there somewhere.

Mmmm.. an update here:

Reverting the drivers/hid directory does seem to improve behaviour.

But right now I have a "make -j4" happening in the background
and the mouse is ever so erratic again, despite the drivers/hid reversion.

So it's a timing thing, somewhere.
Maybe a scheduling thing?

Jiri:  I know nothing about how mouse clicks are interpreted,
or even *where* or *how* double-click detection happens.
Until this started happening, I didn't even know which module
was the driver for my mouse (it's usbhid).

Can you give a short tutorial, to help us understand possible causes ?
