This may be fixed. But if not don't use ReDraw. This causes GRASS to
completely re-render the map. Try one of the following:

add a...
self.mapPanel.Refresh()
...instead of a ReDraw call to onFocus

If this doesn't work,  add...
img = self.getImg()
self.draw(img)
...This will redraw the existing image without causing GRASS to re-render
it.

Applied the patch below, though I used the new event binding syntax

self.Bind(wx.EVT_TEXT_ENTER, self.RunCmd, self.console_command)

I don't understand why this worked OK on my Mac WITHOUT this patch.
Thanks!
