Let's hope that someone else has run across this problem, but it sounds
completely unfamiliar. My own first thought was that it is necessary to update
the graphics driver, but since you managed to get everything to function with
your workaround, that doesn't seem likely.
There's nothing particularly special about sliders -- they just process mouse
events. You might try narrowing the scope of the problem by playing with a copy
of the module controls.py (in C:\Python26\Lib\site-packages\visual), inserting
debugging print statements at critical points. And I would think you should see
problems with any program that does mouse drags, such as the example program
toroid_drag.py or colorsliders.py. The latter program has slider-like devices
but doesn't import controls.

We want to use the machines to develop and run VPython programs. But I find that some of the objects in visual.controls don't work: for example, the slider. (This was observed with the supplied controlstest.py program as well as a program I wrote.)
