Teleporting enemies

[Xaphan.]

Back in the old days I was running the lagtastic old old Port Royal on half a stick of RAM, and about 500 MB of space on my hard drive. I never had this problem


Today, with 770MB of space and 2 brand new sticks of RAM, Pirates runs so smoothly, It's unbelievable. So how come I can never hit the enemies? The enemies move around a lot, so when I slice or shoot where one is, they just disappear from their lagging spot to where they are standing right now. Not liking to turn around slowly every time I attack something, is there anything I can do to fix this problem?
