Enter key gets corrupted

[Theo Band]

Binary package hint: remmina

I can only work about 1 minute with a VNC connection. Then after some keystrokes I notice that the Enter keys does not work anymore. Selection in a text editor seems to be reversed. I can click somewhere but the selection is always extended as if I had entered the shift key. There is no way to unselect (tried this in Nedit text editor). The problem starts when I for instance use tab completion in bash of if I search in less.
I used od -c on a shell to see what key was seen by the application (I have to re-connect to give the final enter). I see that instead of "\n" "033 O M" is send. I think this started after the upgrade to Ubuntu to 10.4

And I expected a newline ....

The connection is made via a SSH tunnel.

This problems occurs if I set the following setting under keyboard preferences:
System->Preferences keyboard->Layout->Options->Miscellaneous compatibility options->"Shift cancels Capslock"

When this option is enabled I cannot use remmina anymore.

I have disabled the option again and everything is fine again.

The reason I enabled the "Shift cancels Capslock" option in the first place was that my laptop misses an indicator (LED) for Capslock. So when in doubt it is enough to press just shift and CapsLock is disabled. But not being able to use remmina anymore is bigger pain. The tool is brilliant and I simply don't want to miss it. A big thanks to the developer(s).
