pasting into 1.4.0.1 inside KDE 4.60

  I've been happily using Dosemu 1.4 under openSUSE 11.1 with KDE 3.9. 
I just moved from 11.1 to 11.4 with KDE 4.6.0.

  Before, I used the "both mouse buttons" method to paste text from 
Linux apps into a DOS text editor.  Now pressing both mouse buttons 
doesn't do anything.

  I uninstalled the 1.4.0.1 that openSUSE installed and then reinstalled 
Dosemu from the same RPM (also 1.4.0.1) I last used in 11.1  No change.

  I tried "xdosemu" on the command line instead of "dosemu".  No change.


  At this point I'm out of ideas.  I suspect the problem is with KDE 
4.6, since the same Dosemu works fine in KDE 3.9.


  Can anyone offer a fix or workaround?
