I installed in on my device, actually I don't even have a card yet.
I tell ya, I could be wrong but I'm really thinking this must be something that is hard coded into the Verizon Launcher programs.
Last night I spent hours going over the registry searching for OperaL, Opera9 and even just Opera and I couldn't find anything that either wasn't already changed, or was completely irrelevant, at least as far as I could tell.
The only thing I wondered about was that there were a few entries in the Task Manger thing which I left as they were all zero'ed from what I'm thinking is as a result of a memory saving cab I installed.
An yes I installed Opera 10 before I installed the cab.
So, so far everything else I know will open Opera 10 but my TF3D Browser tab and Weather Tab if I click on the "more info" will not, which ironically are the very two I would want more then anything.
Have you tried starting a discussion over at http://www.howardforums.com/showthread.php?t=1569119? I did a little looking around but could not find anything.
