workaround/solved? for Win7 Re: Uncommon problems with RDP, clipboard and Windows

I have it working on Win7 - it might be related to fast user switching. I
went to VNC as a workaround and noticed it only worked when I also had
rdesktop connected. If the rdesktop client session was minimized, on
another virtual desktop or not connected, the vnc client session went dark.
This gave another opportunity to Google, where I found VNC doesn't support
fast user switching. I log off, log back in, reconnect with rdesktop and
debug messages from rdesktop console start streaming - copy and paste works
like a charm.

It still doesn't quite make sense - the problem with VNC is that when
rdesktop is disconnect, it seems to switch my login "out".

I'm pretty sure there's at least one person out there who is a bigger idiot
than I, but I did assume rebooting the computer involved logging off.
Rebooting did not resolve the issue, or I somehow repeated some steps that
led me to the same place. I'm not sure how, because there is not even a
keyboard or monitor attached to it, so I always connect with the same
rdesktop bash script. Is Win7 "caching" log on info on reboot as a way for
Windows to start up faster? Explicitly logging off and logging back on
worked. How did I get in this mode as the sole user on the box? When will I
pop back into fast user switching mode? What a pain!

Still, there might be something there for you guys to take a look at -
clipboard compatibility with fast user switching. Or is it just some f'd up
Windows thing? If I can help let me know. Right now, I don't even know if I
can reproduce the problem.

I'm ditching the old dirty WinXP box - not worth debugging.

Thanks for Listening,
Sean
