well, I have this problem too occasionally.
normally caused if its an SP2 machine. never have this problem on sp1
or noSP. also, if I disable the DLA sysyem, i cant access flash disks.
another thing to think about is, what does bash do with $0 or ARGV[0]
? if it sees its "bash" then its gonna act differently than if its
"sh."
just a thought...
