Don't worry about it , I used to have the same problem in my Milestone , now I'm just using Dolphin HD , its better than Opera
Faster , space efficient (if you have 130 mb only for apps) & you can save pages & images
I can't say the same about Opera in my E75
I like Dolphin and Skifire...specially because of the fact that they display Adobe Flash content on the webpages unlike Opera/Firefox. The advantage with Opera is speed, due to its compression technology.
Dolphin is good since it's the only browser I know that uses flash but Dolphin does not have text wrap and Opera is the only browser that I know that has that.
