#1635 Activated SCROLL LOCK prevents use of ALT KEY on the remote side

[M. Soelter]

If SCROLL LOCK is activated on the viewer PC, you cannot use key combinations with ALT on the remote PC. The ALT KEY will be ignored.

Because I have not found any information about this and the connection does not seem to be particularly logical and a solution is therefore difficult to find, I wanted to at least publish it.
