issue when pasting large text into textarea field in a browser

this happens in firefox and Opera as well as ie7.

Smaller amounts of text paste fine but text with a few thousand lines of
pure text will not paste. The system just feezes

I could do this in Xp and W2000 but in Vista it just will not do it.

Anyone know what to do???? I have vista home premium; I am considering
removing Vista and going back to XP or 2000. I have just bought this on a
Dell and did not get the choice of choosing XP I hope I don't have to do this
I cannot really afford to pay 150 pounds for XP.
