Zip on Vista: sucks

Yeap, just like that, it takes for ever to unzip files, I don't know why, and this has been like this from day one, apparently, the Service Pack 1 should have taken care of this... But, I did install the Service Pack, and I haven't noticed any improvement whatsoever.

I mean, take a look at the screenshot... 4 minutes and a half to unzip an 800 KB file... That's like way too much...
