It would be nice if the status of the caps lock on the remote machine were automatically updated to the status of that on the host machine when connecting. This has caused confusion for many of our users as if the caps lock is off on the host machine and on on the remote machine, the caps lock on warning is displayed on the Windows login screen even though the keys being sent from the host machine do not have the caps lock on. Users will often press the caps lock key to turn off the caps lock on the remote machine, in turn, turning it on on the host machine, and causing their password to be entered incorrectly. We've had to instruct our users to ensure their caps lock is off on the host machine and disregard the warning on the Windows login screen on the remote computer.
