Len Pitre updated his homepage with the following announcement (I'll quote since this might turn out to be kinda important):
If you have recently had any hard drive problems, I'd like you to sendme a list of the various Doom-related programs (editors, source ports)that you use.
Why? A friend of mine has come up with a theory that could mean thatmany people using a certain Doom-related program under a certain OS areat risk of hard drive problems, but I don't want to make unfoundedaccusations.
Please note that this is not a malicious trojan. It seems to be a bugthat corrupts an important part of system memory, which, in turn,corrupts the boot sector, MBR or partition table.
Ooo, a mystery!
