Hi Stephen, I tried your suggestion but alas, it's still a problem - must be MapInfo. Looks like a rounding error in the mapinfo display code that decides where to redraw the map areas that have changed. The error causes the area to be replaced one pixel out of place, hence you get a sort of 'jiggling' effect which is quite offputting. I am using MapX to dynamically create features on a layer. The features' positions change rapidly, so the effect is very noticable.

This will usually be under "settings - Control Panel - Display - Advanced -- Troubleshooting" Or something similar, depending on Windows version and PC settings . I generally set Hardware acceleration somewhere between 25% and 50%, using the slider bar.
