Hi Huidae,

thanks a lot for your answer.

OK, the -r flag is not shown in the tcltkgrass module and in the
html-manpage. So i overlooked that. 
But i still think that it is a bug (or at least an inconsitency) that
the window is redrawn with d.zoom/d.pan, but the color of the vector is
changed to white. I think that d.zoom/d.pan should either always redraw
the correct screen or don't redraw anything at all without the -r flag.
In that case the user can first use d.save, then d.zoom/d.pan and then
redraw the screen without waiting for the "wrong" redraw of
d.zoom/d.pan.

Just how i would like it.

It would be nice if d.zoom and d.pan behave identically, otherwise it is
confusing. 

cu,
