This morning a handful of workstations got upgraded from 6.3 to 6.4 and things seemed to be functional, until we tried to log in to one of our instrument accounts that for various reasons uses olvwm/openwin as the desktop (and no, I don't have the option of changing that at this time). The desktop appears to load correctly, and mouse-focus and clicking appears to work, but the .openwin-menu entries no longer function other than clicking "exit" to log out of the session. I've tried reinstalling xview and xview-client rpms, but that doesn't resolve it. I don't think it's an issue with the user account, as the underlying commands work when I su and execute them in an xterm. I was also able to reproduce the problem on three separate computers.
I don't usually have to deal with these desktop issues so I'm hella rusty when it comes to debugging them. Does anyone have any tidbits to point me in the right direction to fix this? (Hopefully soon, since we are supposed to use this account for observations tonight)
