We upgraded architect project to 2.2 now we are having these issues:
1. When clicking Publish, the new publish log view (I am not sure if i call it correctly but i am referring to the view that shows in replacement to the old command prompt) can't be closed without either dragging it a bit then pressing escape OR closing the entire Architect.
2. Let's say on #1 I pressed escape and was able to close the view and then i hit F6 to preview, the Project Preview view will appear. it can't be closed by clicking any button nor the close button nor the escape key. The trick will be restoring (from maximized) the Architect then pressing the escape key. This only happens when you are trying to preview after a publish.
We were able to find workarounds for this after a day or so. However, the initial impression that the Architect 2.2 will give to anyone who had been using the previous version for quite a while can be troubling.
