im having the same promblem! I've only had my tab, arnova 10 g2, about a week and i set about rooting it with the latest firmware avoiding updating flash from 10.3 to 11 because of the horror stories i heard. anyway once i'd finally got market installed it automatically updated flash and thats when it started doing this. ive noticed that opera browser doesn't close but all the others do! (dolphin etc) i dont think its a coincidence that opera doesnt rely on flash and that works fine! if anyone knows how to downgrade flash then let me know coz im sure thats the culprit. maybe its not but im pullin my hair out over this i can hardly do anything with my tab!!! please help!!!
