Error in app with TabNavigator loaded with SWFLoader - WebKit browsers

Question

Hiya,
I use a flex app (A) to load another flex app (B) using SWFLoader (both built using Flex Builder 3 sometime ago).
Everything works fine as expected across all (IE, FF, Chrome, Safari) desktop browsers.
However, if I use a TabNavigator within the flex app (B) then when you click on any of the tabs it unloads the flex app (B) and re-starts flex app (A). This behaviour is limited to Webkit based browsers (Chrome & Safari) the rest of the browsers (IE, FF) it works fine.
I wonder if anyone can throw some light on this.
Many thanks
Kind regards,
klem

Resolved:
Replacing the HTML template files with the latest copy from Flash Builder 4.5 seemed to resolve the issue. It appears they have replaced the AC_OETags.js with swfobject.js
Tried to explore upgrading the code to 4.5 but seemed to throw a lot of incompatibilities, created a test/dummy project instead in 4.5 and used the html file created to replace the old html files created by Flex Builder 3.0
Clearly not a very common problem, but hope this saves someone time and effort.
Thanks Harui
