Please report how you converted the data. Your experience is valuable to 
others, and if you keep it to yourself, please don't be surprised is 
others won't share theirs with you, seriously. Yes or no: you moved the 
48M *.mdb file to a Windows box and converted it there using ogr2ogr? If 
no, how did you do it?

So maybe don't zoom - the mailing lists are full of reports like this 
about CPU usage. Use g.region to reset your region of interest and re-display.

There are several (many) display mechanisms, and so far you haven't said 
which OS (distribution/Tcl-Tk version/...) you are using. This is GRASS, 
everything can be done, but maybe not the first way you think of.

An affiliation would help too ...
