some people wont think this post is relavent, but I am seeing a
pattern here, but am unsure where it leads.

I have had the exact same problem with an MSX emulator. Both key
repeats and sticky shift keys.

The pattern seems to be related to keyboard handler, or keyboard
(emulator) timing.

Is this ever known to have sticky keys or repeating keys on a standard
Atari ST/STe/Falcon?

Also, I understand why I may be getting the problem, and wounder if it
is also a related issue for others, and that is the use of extended
characters or key tables (eg using " + e to get an e with double dots,
etc where " + space gets you the actual " character)

Also note, use latest (helmut) kernel/xaaes (and maybe combo with
Alans hex patch, for CT)

cheers
