I installed your new version, but now, all those commands that still use
"exec" are missing the "&" and block the entire tcltkgrass menu while they
are active. When I click on "close", I get an error message (example of
r.sunmask):

child process exited abnormally
child process exited abnormally
    while executing
"exec r.sunmask"
    invoked from within
".main_menu.mb3.m.m9 invoke active"
    ("uplevel" body line 1)
etc...

This is also true for the d.mon commands which makes them unusable with
the tcltkgrass menu.
