intermittent Permission problems with bash

[Hassan Blurfrushan]

When running shell scripts on my NT 4.0 workstation
using bash, intermittently I get a "Permission
denied" message like this:

/usr/bin/sed: Permission denied
/usr/bin/tr: Permission denied


This happens very intermittently and since upgrading
to "beta18" (from beta17.1) it is happening more 
often. I looked at faq and message archives with no
luck. Any help would be greatly appreciated.
