Windows problem

It appears that every time I try and run CU-SeeMe under windows using a
ComputerEyes/RT digitizing card (msvideo and all appropriate video drivers
installed), I keep getting a General Protection Fault when the program
accesses the weyesrt.dll for the ComputerEyes/RT card..

Here's a Dr.Watson log (in case anyone wants to know the nitty-gritty
details of the crash)...anyone else having this problem? I can get CU-SeeMe
to work fine if I don't use the digitizer card...I tried the latest version
of CU-SeeMe..as well as all the previous versions...to no avail..

Thanks for any help.
