I agree with Helena here. Thanks for all the recent fixes. However, the common import dialog/wrapper for r.in.gdal and v.in.ogr still has a number of problems. 

Perhaps we could just stick with the original module dialogs for 6.4 so that there is time to get this custom import dialog working well. I can see how it could simplify the sometimes puzzling syntax of v.in.ogr but I'm not sure that it is any easier to navidate than r.in.gdal even if working right.

I can test again, but this works for me on the Mac. The key, as you surmise, Helena, is to have the resolution of the display match the computation region resolution so that when you zoom in, only a few cells are displayed. It took a bit of playing with this, but I got it to work recently.
