Yup happens all the time,
 also with alt tightvn-vnc ( which has a nice button to put it back)
(
I always end up with alt depressed after alt-tabb-ing round to a session
even tho I released alt :("

I've seen it with just about every remote etc

Hmm well sort of there is.

Method No.1 is to have a script on the NX server to switch it
independently of the client . . .

You can probably download one, I haven't felt the need yet.


Method No. 2 - catch the right moment to switch the client caps lock

The two ends start off a connection with the
        then current state of num-lock shift-lock etc
then
        monitor key presses
so
         sometimes a key press gets missed if occurs at the wrong time
so
if you hit connect in the nxclient with caps lock
then
UN-CAPS LOCK just as the X session is starting, (after authentication)
you can get the session to miss the key-press.


But you'll need to try a few times to get to know when to do it.


NOTES
I've seen a few instances with the OpenNX client against Opensuse 12.2 
where
I couldn't reconnect at all if there was a mismatch
         i.e I hit caps lock by mistake in the session then disconnected

(just tried it again and got

Loop: PANIC! Can't identify NX port in string ':'.
Error: Can't identify NX port in string ':'.

followed by an actual re-connect, but with the WP top menu fonts
all messed up.

BUT
I wouldn't say that 12.2 was a typical distro version tho
and
I've slightly modded my OpenNX too
but I can't be bothered going through the source with
OpenNX in its current state)


A good fix is to disable caps lock which is mostly useless,
if not most useless.

(I guess that 99%+ of caps lock use is by accident
With me it's 100%
( except when testing caps lock issues))

see
         http://capsoff.org

but of course
that doesn't solve alt and ctrl issues
