Clipboard problems

Hello.
In complement to this problem, I've tried some tests :
  1/ I've checked out the cvs tree and compiled a debug version.
     I've used it but the behaviour was the same and I didn't manage to find
     how to track the culpid, due to the integration into KDE-Cygwin.
     I think the problem is strongly related to KDE clipboard management, so
     I also send this mail to the KDE-cygwin mailing list.
  2/ As ever, I've regulary updated my cygwin installation and retried.
     Until 6.7.0.0-8, there was no change (unless cursor desappearing, temporarily
     solved with -swcursor). But with 6.7.0.0-9, ther is some evolution :
     Now, the clipboard works fine as long as I stay into X11 applications,
     but as soon as I try to use it into Windows applications, XWin freeze,
     with task manager showing 100% of cpu consumption. The only solution is to
     kill it manually.
How could I help you tracking more efficiently this problem, or even how could
I solve it ?

Thanks.
