If you want to see what happened last time I updated those drivers:

Actually.  Historically, I have heard (and experienced) that ATI's driver support for GLSL is very poor.  It may not be that the GPU can't handle branching but that ATI's GLSL compiler can't.  Cg may actually work much better because it involves a compiler separate from the driver that can translate the code into ARB assembly (with extensions for branching and so forth) and feed it to the card.

If it works on your machine, I'd like to hear of it; if it doesn't, I'd also like to hear of it. For reference, my setup is an NVIDIA 8800 GTX (beta drivers) on Windows Vista with an Intel Dual Core 2.66GHz processor. I can confirm that it doesn't work on an ATI Radeon 9800 on Windows XP.

The mouse wheel selects the current variable, dragging the left mouse button changes it (enumerations and floats are changed by dragging to the right or left), clicking the middle mouse button resets to the initial value, and right clicking returns to zoom/scroll mode.
