My PC is 1.60Ghz with IGb of RAM and I have no problems. The machine spec, as defined in the manual at page 6 is Microsoft Windows, a PC with 400 Mhz processor (higher preferred) 128 Mb RAM and at least 50Mb hard drive space and a USB connection. However, I have seen elsewhere reference to a processor of 2.0GB minimum being required so perhaps the requirements need to be set out again.
