[GRASS-dev] r.patch problem in wingrass

I'm using the wingrass63_cvs20070615 version of wingrass on a Vista machine. Looks nice, works like grass!

But when I try to use r.patch I get the following error message as soon as I choose the Patch maps menu item.

couldn't execute "r.patch": invalid argument
couldn't execute "r.patch": invalid argument
    while executing
"exec -- $program --tcltk"
    (procedure "run_ui" line 6)
    invoked from within
"run_ui $cmd"
    (procedure "execute" line 3)
    invoked from within
"execute r.patch "
    (menu invoke)

Any help appreciated.
