IE7: window.createPopup leaks 80KB
Ха-ха-ха-ха! Това е егати излъгациÑта ;)
We at FCKeditor are constantly fighting against memory leak. We have already fixed several related issues, but we were still facing an expressive memory leak with IE7.
With some intuition, we were able to reduce the problem to a simple test case, and we have sadly found a new memory leak issue *introduced* with IE7.
