Unless there's something wonky about my setup, there seems to be a pretty serious memory leak when I do anything with the 1.4.x branch in IE7.

I'm running IE7 on XP SP3 with the latest patches in VirtualBox. The problem occurs even when running in "Safe Mode".

When I include an older version of the library, i.e.

And create a new HTML file and simply put something like this in the body:

When I open IE7 and keep the task manager visible, I can refresh over and over again and nothing happens -- on my setup memory use hovers around 35-36MB after several dozen refreshes.

However when I replace the library with anything from the 1.4.x branch (I've tried all of them including the nightly build), i.e.

When I do the same thing -- go the page in IE7 with task manager open -- with each refresh the memory usage climbs. It doesn't take long before it tops 100MB. Eventually I need to kill IE via the task manager because it stops responding.
