[GRASS5] window size

[Sabah Yunus]

Hi,

I am running d.rast.num in grass 6.0 and I get the following error message:

Your current window setting may be too large. Cells displayed on your
graphics window
may be too small for cell category number to be visible. Do you wish to
continue?

I have tried many commands to change the size of the window and manually
also tried but
to no result. Could you please let me know how I can get rid of this
error message.

Thanks,
Sabah
