Yes the same thing happens when the disk is being accessed heavily for any
reason.
Mouse pointer seems ok.
I have two physical hard drives in my system. One has Windows and the
other is split between Linux and a FAT32 partition that holds the compressed
EGTBs.
I am using Mandrake7.2 (final) as supplied. Kernel 2.2.? (14 or 16 I think).
Thanks for the interest.
