Hi Aesir,
This is a whole mess of a problem, really. It's partially dependent upon the ad what actually happens. I WANT it to open in the system browser. For some VMs it does, and for some it doesn't. On top of that, it also seems partially dependent upon the ad itself.
I think I'm going to move to webkit post-beta which should remove this issue. Until then, it will remain.
I'm not going to fix this before beta, because it's too complicated of a fix. I do plan to standardize it, though.
As for bug reports in general, if you could post them at
http://www.mmoui.com/bugs that would be great. They will catch my attention better that way and be sent to my blackberry.
