d.zoom

Hello GRASS users,

Lately when I go to zoom in on an area
(using the d.zoom command). The graphics
display monitor disappears and the following
error message appears:

X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 73 (X_GetImage)
  Serial number of failed request: 4274
  Current serial number in output stream: 4274
ERROR eof from graphics driver.

any ideas??

Thanks in advance
Mara
