2291	AutoIt causes memory leak?	aimlezz-Mike@…		"Hey guys,

im writing on my project and got some memory leaks. Actual im looking for the leak for a month and now i got some curios results.

I wrote some testscripts, to see, if AutoIt causes memory leaks. So i wrote some testscript for Listviews, Lists, and Labels to see, if i create a Listview with lets say 1000 items and delete them, does AutoIt reset the complete memory of these items? i'd say no. I did some tests and got the result that in best case 4K memory is missing ...
