cpu usage problem

i've noticed that after a while of using SmartFTP, my system would grow sluggish. Upon checking task manager, I noticed the culprit was SmartFTP! It was eating up 90-99% of my system resources. I know it cannot be my computer (athlon xp 1800+, 1 gig DDR ram, etc) It seems to only happen after I leave a large number of sites connecting ( that i cannot log into right away, retry at 61+ seconds ). Right now I logged into one and am downloading a file, and even after closing all of the others it still uses 98%+ of my CPU cycles. Any ideas?

btw, exact system specs are :

[ windows XP professional, athlon xp 1800+, 1gig DDR ram, 100gb hd, SmartFTP version 1,0,973 - though i've noticed this in previous builds as well]

Please upgrade to the 976 official release, which has been out for a couple of weeks now.

Online Setup:

Full Setup:

This problem has only been reported for the 973 official build and earlier, under abnormal
circumstances and has not been reported for the 976 official or the 977 developer builds.

So to break it down, It was a very hard problem to reproduce when it existed

makes sense.
