Hello Sergey.

I appreciate your suggestion.

I could start talking with AIX GUI experts about this issue.
I'll let you know when the situation is changed.

Since CDE is the only desktop environment running on AIX platform,
please maintain the current support level of CDE / MWM.

Thanks,

I found the fix against dtwm/mwm on AIX platform, but it did not work on Linux's mwm.

Can you please clarify why it doesn't work on Linux? It would be
better to minimize platforms specific code.

I guess that the problem is that the non-focused window is looking
like the focused, but in fact, it is still unfocused and none of its
children can be focused as well? Otherwise, I think some of the tck
tests could fail. If that's correct it is unclear if this problem is
important and should we as a fix inject more platform-specific code to
the XPeers. Since the CDE is unsupported by AWT for a more than 10
years I think the issues are not critical.
