Draftsight crashing on startup

Hi,

I have a Dell D430 running windows 7 32 bit and have tried to install Draftsight.

I was able to register/activate  Draftsight ok but now on launching the app I get as far as the draftsight Alert window and then the app crashes.

In event viewer the faulting module is ig4icd32.dll which I believe is part of OpenGL for the intel 945 GMA video driver.

Tried the latest Dell and MS and Intel video drivers, all with the same results.

Tried all the usual uninstall/reinstall, delete from c:\\users\\..\\..\\Draftsight etc.

Any ideas on how to get Draftsight to work?

Thanks,

Andy.
