	But then I have to hook up an LCD to it. ;)

	This has been the case.

	I would but then I'd have to setup some additional firewall rules. :P

	Excellent idea!

	Good point.

	My initial googling found that this behaviour was common. :(

	I haven't read any reviews. I thought that 6.10 would be better 
overall. Other than this minor issue, I've been happy so far.

	Well while I looked at the TERM environment option, I found an answer 
that worked. Install the vim package. Go figure. Now I'm thinking maybe 
I should export a list of installed packages on the 6.06 to compare with 
the 6.10 machine.

	Any ways, thank you all for the help tonight! Anyone know what that 
white stuff is outside? ;)
