Xclient with xming on MSW to HPUX X11 / VUE 10.20

I was looking for a free tool to use a xclient on my Notebook to work with my CAD program on HPUX.

I found and installed Xming and xlaunch - very nice an easy, after configured it connects to my HP C3600 WS 10.20 and I get the vue login. I can use the complete vue - only the right mouse key doesnt work ! So I cant move hpterms, cant size them etc.... someone who has an idea ?

:confused:

I happily use Cygwin's XWin fronting HPUX 11.11.
