HighGrounds, back in July you described symptoms close to something I have observed. Specifically, when I do a clean XP build (w SP3) updated, then add dotNet Framework 4.0 (updated) then install Plan-G, I find that whenever I move the mouse pointer over the map area of the display I trigger a script error which reads "An error has occurred... Line 87.... char 25... Error: Unable to load DLL "sqlceme35.dll". My solution is to install dotNet Framework 3.5 SP1. This fix has been successful for me twice. :)
