Hi,
it looks like the Browser 7.3 has some Problems with jQuery Mobile (http://jquerymobile.com/)
The Browser crashes if it opens pages which use jQuery for mobile devices.
Tested with Nokia E72-1.
Try it yourself:
http://jquerymobile.com/demos/1.0/

Tested userAgent was:
--------------------------
Mozilla/5.0 (SymbianOS/9.3; Series60/3.2 NokiaE72-1/073.001; Profile/MIDP-2.1 Configuration/CLDC-1.1)
AppleWebKit/533.4 (KHTML, like Gecko)
NokiaBrowser/7.3.1.26
Mobile Safari/533.4

Can anyone confirm this?

Regards,
Bernd
