Your G4 450 with nearly 500 meg of RAM may part of the problem You need at least a faster machine more ram and tons of hard disk space. I use a G4 857 with 1.5 GB of ram and 42 GB of hard dik space. Before with My IMAC Ihad that problem all the time. Also the is a plug in called poser speed bump that should help. VIcky llikes and demands lots of ram, hard disk space and the fastest processor you can afford.. She is very demanding.
