shadertest.c crashes at startup 7.07

Hi,
When i run "shadertest.c" it crashes after the engine startup window opens and compiles the script. There are no error messages displayed in the startup window. The crash happens just after the startup window changes size and becomes the Gamestudio window, then i get the error "acknex.exe has stopped working.." sorry i don't have any other debug information. All other lite-C samples run fine. machine specs: Win Vista32, ATI X1950Pro - Cat7.11

Run it with -diag, and post the acklog. It's possibly an ATI driver bug that prevents you from running shaders on your machine.

ok, below is acklog.txt

not sure if it matters but, i have been able to run all the shaders from the shader workshop with no problems.

It looks as if the crash happens when rendering the panels the first time.

I'll check if I can somehow reproduce it. If someone else has a similar problem, please also post here.

mine working on test run but not working on compiled....
here is the log :

it may actually be a shader causing the crash. I think i have isolated it to something in "mtlView.c" not sure yet...

here is the offending shader..

Code:

---

MATERIAL* mtl_sobel =
{
	effect = "pp_sobel.fx";
}

---

Hmm, I can see nothing unusual in the sobel shader.

The program does not crash when you outcomment the 'effect = "pp_sobel.fx";' line?

I don't get a direct crash on startup, but after playing around for a while, some shaders begin to flicker and look completely wrong. After a short time, the viewer will slow down the whole system until nothing works anymore.
After I managed to close down the window (which needed about 3 or 4 minutes), any DirectX Application was not working anymore - I needed to reboot the system.
To me this looks like some sort of overflow when changing shaders too often?

I'm using a Geforce 7900GT.

works fine when i comment out the sobel shader. i haven't had time to dig into the shader and find the problem yet.
