Hi, after some debuging...
I have discover that the problem occur only with WPF applications... (at least) ...
I think that WPF is using DirectX shaders, but I'm not sure it is related to the "compilation" !
I join a sample appilcation that you can use to see the problem....

After upgrading my drivers (which were apparently buggy), this is the solution to the intersection test.
Kernel signature is:
It should be:
Unfortunately, I have no WPF machine ATM. Can you post the error that occurs?
Does the modified example work from the console?

Yes,
This version work fine.
WPF machine ? You just need to install the .NET 3.5 (or 3.0) framework.
Take a look at the following post : http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=123091&en...
I have send the problem to AMD... maybe the problem reside on their side... can you check it please ?
Thanks

I've never felt like using WPF, I even thought it was restricted to Vista or 7, funny that.
Your code runs fine here. Can you post some environment information? OS type, 32 or 64 bit, etc.,
You might also give it a try with the latest revision from:

Yes, I know. The code is in the OpenTK repository :). Note the URI I posted earlier. I've been having problems with my own repository.
Here goes the zip...
Edit: Try building another program in that WPF application. Like the one from the "vectorAdd" example... And post the results.

This should be fixed in 0.3.1+. If not please reopen.
