AW: AW: AW: AW: AW: AW: AW: [rdesktop-devel] Problem with keysyms returned by XLookupString

[<m.w...@wo...>]

Peter,

I also think this is a Xserver bug - or is XGrabkeyboard supposed to
alter the way in which X translates the keyboard inputs?
After reading the manpages I don=92t think so (but I am far from being =
an
"Xlib expert).

I checked with another system (netstation 0.9pre3), there I see no
problems with AltGr - with our without -K.
Bacause this (netstation) is the target system I can live with the
problem on my development system (SuSe 7.2) - maybe when (if) I update
the X Server, the problem goes away there also.

Thanks for your assistance,
Markus
