 Hi,

 there's a Xdriver rendering bug when calling d.menu, after it is complete
 it should restore the monitor to how it was before the module started, but
 there's something wrong in R_panel_restore() in
 grass6/lib/display/popup.c. Instead of restoring the saved rectangle it
 restores X-buffer junk.

 i.ask and d.barscale use similar R_panel_*() calls and they work fine.
 Coords in the panel's .tmp/ file looks ok AFAICT. It's pretty simple
 function usage but I can't seem to see what's wrong.


 example for r.li.setup:
 {{{
 d.mon x0
 d.erase
 d.menu bcolor=aqua tcolor=black << EOF
 .T 20
 .L 20
 Next select area with mouse
           [ Ok ]
 EOF
 }}}


 bug is present in at least grass versions 6.4.2-6.5svn.

 ?

 thanks,
 Hamish
