I did a complete re-install over the weekend - updated the kernel to the
newest version (2.4.22-1.2194.nptl_50.rhfc1.at) and updated all my kernel
modules.  I'm still getting the same problems.  I'm really not sure what
I'm doing wrong or where to even start finding out!  Can anyone help?

Thanks again,
Jeff
