How much memory does your machine have? I had similar problems on some older systems when utilizing ECDIS systems (A charting program for ships) that was resolved by adding additional RAM. In my case taking the total RAM from 128K to 256K.

I have some machines that work fine, but other that don't. The problem seemed to appear in MapInfo 5.5 (I could be wrong), and seemed to be worse in MapInfo 6 (I don't have 6.5 to compare with). You could try updating you video driver, this has worked for me in the past.

I previously used a much smaller and lesser spec machine to run mapinfo without problems, but now (I mean yesterday and today I am having these problems, when previously they didn't exist) Thnaks for the help.

My problem stems from the use of a raster backdrop which I am using to digitise local roads off. When I pan across the screen to continue a line, the screen partially refreshes, with the part of the screen which was not previously visible repeating the raster and linework that was previously in that position on the screen. Does anyone know how to get around this problem? I seem to remember some consultants up in Cairns do not screen digitize anymore because of this problem. I don't know whether this was the ultimate conclusion, but any ideas would be gratefully received.
