Tooltips issue on IE9

Hi everyone,



i have a scenario where a page needs to load an iframe in a normal ext modal window (due to legacy issues) on a given button click.



On a particular case, where the contents loaded onto the iframe also use Ext, i'm having an unexpected behaviour on IE9 where all the tooltips on the parent page stop working after the window close (which doesn't happen on FF).



If i remove the ext-all.js include from the page loaded on the iframe the issue doesn't occur, so i'm guessing the ext included inside the iframe is somehow impacting the quicktips configuration on the parent page on IE9. (Both the parent page and iframe are using Ext 4.2)



Anyone has any ideas on how can this be prevented?



I've tried re-enabling the quicktips on the parent page on the window close, but that didnt have any effect.



Thanks in advance for all ideas, and i'm sorry for not being able to provide a code example, but the same origin policy on the iframes is preventing me from replicating the issue with publicly available content.
