My Suite 2009 has slowed to the point that executing any command takes multiple, double-digit seconds and my "dream house" file size has ballooned to 188Mb. I don't import any imagery other than the architectural fixtures resident in the software's library. I'm running it on an HP TouchSmart 610, Win 7, i5-2400, 3.10GHz, 8Gb RAM, 64-bit processing. The situation has reached the point where I no longer enjoy using the program. Advice?
