This appears to happen because screen does not create a window until AFTER the rc file has been processed. This is an issue because the user has no way of knowing that all the commands have been ignored.

Screen needs to warn users that commands are being thrown out when there are no windows to act on.

I checked the debug output and screen interprets the command from the rc file but does nothing with it. When the user types in a command, manually, then it actually runs the command.

DEBUG OUTPUT:

-- Reading from RC file --

FindUserPtr guest found, id 1
UserAcl: user 'guest', no password:AclSetPerm(uu, user 'guest', mode '-w', object '#?')

-- Reading from session --

FindUserPtr guest found, id 1
UserAcl: user 'guest', no password:AclSetPerm(uu, user 'guest', mode '-w', object '#?')
AclSetPermWin guest -w 0

Using a "screenrc" file (via -c option or the default) does not execute commands as expected.

example:
acladd user
aclchg user -w "#?"

This will add the user but the second command does nothing.

"writelock on" is also ignored.

If these commands are entered manually, screen behaves as expected.
