Do you have your Xastir built with "rtree" support? Rtree support (which is currently the default) does speed up zooming and panning after the first rendering of a shapefile (by creating a spatial index of shapes in the file so it doesn't have to check every single shape to see if it's on the screen). Do you have "auto maps" turned on (you shouldn't)? Sometimes this is the cause of unreasonable loading behavior. The only files that should be getting loaded at any zoom level are those that overlap the screen, so if "all the files" are loading, there's something goofy. How big an area are you attempting to view? Does it include a large number of counties? -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM "The truth will set you free, but first it will piss you off." _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
