Lenny: mouse srewed in OpenGL application

[Tim Gruene <tim@runnwerth.net>]

Hello,

I hope I picked the correct list for my problem.

I recently installed Debian lenny on a Pentium 4 with Radeon 9800 Pro 
graphic chip.

Everything worked fine as usually until I wanted to use a graphics program 
which uses OpenGL.
Amongst others, the program accepts the following mouse actions:

Centre-click on a displayed point centres on the point
Ctrl-righ-click moves the scene sideways.

On this installation, the centre-click is responded with "Atom pick 
failed" and nothing happens, the Ctrl-right-click results in arbitrary 
jumps far, far away from the current view point and a distortion of the 
view.

Today I noticed the same behaviour on my laptop where it definitely worked 
until recently (unfortunately I don't know, HOW recently, otherwise I 
would check what has been updated since).

Both machines use the ATI prorietry driver, but I also tried the ati and 
radeon drivers.

I am quite sure it is a software error related to the (Debian) system 
rather than the program because the problem persists if I open the program 
through an ssh tunnel from another machine but disappears when done the 
other way round (started on another machine opened on mine).

I would appreciate any hints and ideas how I could trace back the problem 
and solve it.

Cheers, Tim
