Hah, I guess it's kind of a "bug forum". But really it's the bug tracker. If you want to share your experience, it might help to move things forward a little -- especially since none of the potential fixes or workarounds worked for you. Who knows, maybe something about your experience will give developers a clue that they didn't have before?
If you want to follow the progress of that bug, find a text link in the column on the right, to subscribe and be notified about changes to the report. Just click the text link (it will change from saying you are not subscribed to you are).
Personally, I would post in the 2nd report that I mentioned, the much smaller one, because it's about the dual monitor setup, while the other one seems to happen to be related to having other programs installed (although note that I did not read that long one very closely). Plus, none of the workarounds for the other one worked for you. But it's up to you which one you post in. After all, the smaller one has not received much attention from developers yet. If you do post in the smaller one, be sure to mention the other one, and that you tried everything there, without success.
