After running or whilst running a program like DVD Player or Illustrator I have noticed my Powerbook running really slowly often freezing up until OSX sorts itself out. I checked my iStat widget and looked under memory and it showed that there was about 400-600MB of inactive memory which normally isn't there (I Think?) and only around 30-90MB Free Memory. My PB has 1GB DDR2 Ram so I think it should be able to handle it as this has only started to happen recently. Does anyone know why this is happening or know a fix for this problem?

Note: I did upgrade to 10.4.6 could this be the cause?
