Flexigrid - Lightweight but rich data grid

[eluser]pinkhominid[/eluser]
Paulo,

I am using flexigrid in a single-page thick-client ajax app that does not do full page postbacks. In this context I have found that flexigrid leaks a pretty significant amount of memory in IE. An instance of the grid with all the bells and whistles (example 3) leaks about 2-5 MB of memory per execution of the flexigrid() method.

Because of the way IE is designed this memory is not freed with a refresh or by closing the tab. It is only freed when all instances of IE are closed.

I've put together a bare minimum demo page that shows the leak. Look at it in IE6 or IE7 and click the 'new instance' buttons multiple times while monitoring IE memory consumption. Each click empties the containing div (using jQuery's empty() method) and creates a new flexigrid instance.

Also, I've tested Firefox & IE8 beta...they DO NOT have the problem.
