I agree with Valandar. A lot of criticism floats around here about P5. It does need RAM and sure, there are things it could do that it doesn't, but I too am a proud owner of this software and I really like it! I have a 1.2 Athlon, with 768mb RAM using XP. If I were you, I'd add a modest amount of RAM now and save for a system upgrade to something like 1.8-2.2 Mhz.
