Reposted: Memory leaking & Sikuli script crashing - Windows 7 & XP

This is a second attempt for an infinite loop and my script is throwing again an "insufficient memory" error message after 20-30 minutes of activity. It happens in Windows 7 (Home edition) and Windows XP. Here is my code..perhaps there's something wrong with it although I don't think so:

while True:
 switchApp("Internet Explorer")

 if exists(<image>,1):
  click(<image>)
  wait(6)
  click(<image>)
  paste(<image>,"http://www.google.us")
  wait(3)
  paste(<image>,"http://www.yahoo.com")

 if exists(<image>,1):
  paste(<image>,"http://ebay.com")
  wait(1)
  type(Key.ENTER)
  wait(1)
  click(<image>)
  wait(4)
wait(1)

And, here's the error that's bugging me for few days (taken from the command prompt - cmd.exe) - I also get a window with a runtime error:

...

...
[sikuli] click on (76,163), MOD: 0
[sikuli] click on (302,61), MOD: 0
[sikuli] type "
", mod: (0)
[sikuli] click on (76,163), MOD: 0

C:\Users\Me\Desktop\clickRefresh.sikuli>

It will be useful to know what I am doing wrong because I looked all over for an idea and beside making the script smaller, I don't know what else I can improve. The waiting time between clicks/typing/pasting should not be a problem I'd say and I really would need even smaller times.

Thanks!!
