Did you post on the forums or on the bug tracker.
There is no need to fix these bugs on your own report them and they will be fixed in the main copy.
Please post them here.

If we all report all the bugs we find then they will get fixed by the VB staff. That is the whole point of posting a beta to the public is to get our feedback and report issues. So they can have almost perfect software for a gold release.
