Memory Leaks In jQuery UI Should I be Worried?

Memory Leaks In jQuery UI Should I be Worried?

I have spent the better part of 3 days trying to resolve an IE only memory leak in a custom ui widget. It involves cloning an image and removing the original.

When researching this I went back to the jquery ui website to look at modals to see if they had a similar problem. On the modals example page... if I open one modal then switch to another modal... then repeat.... I see the memory usage in task manager steadily increasing.

So a couple questions:

1) Am i seeing a memory leak in the modal or is the example not "cleaning things up" like you would in a real app

2) If that is a memory leak, should I be worried?

3) Are there any best practices with jquery ui for avoiding leaks, especially when it comes to cloning/inserting/removing content

Thanks!
