We now have two seats using Windows7 64 bit, and Map 2010. When plotting large aerial photo images (tif, ecw, sid) the PC hangs up for a couple minutes processing the plot. On an older 32 bit PC the plot goes much quicker. Seems odd that the high power 12Gb RAM 64 bit PC would be slower?? Since I am new to Win7 and 64 bit, are there any suggestions or tips to help me get faster image plots?
