The issue is only around a specific website - sale car ads http://www.autotrader.co.uk .
The problem is around browisng the photos in the ad - if there are multiple, browsing quickly through them makes maxthon freeze around 10-15th photo or so. To unlcok I need to go t another tab and come back, still freezes when I wanto to further browe photos. Very annoying as I use the site often.
Happends on both Ultra and Retro core.
I've encountered this bug many times.
