hey im running os 10.3.9 on a g3 imac (600 mhz, 256 mb ram, 40 gig hd) and for some reason, when a popup menu appears (not a popup ad, a menu) such as autofill in safari, the program in which it happens, freezes and the color wheel spins. it doesnt stop. I then need to force quit out. can you help me fix this? thanks.
