Hello,
I am currently using grass61 under cygwin on a Dell Inspiron 9200
Centrino with 2G of memory and this is a very serious problem!
Trying to use i.points is painful and not worth the problems. Waiting
for the redraw or the zoom/box to draw on the screen can take over 30-50
seconds.
So there is confirmation. Hope this can be easily fixed.
