Bug - While dragging from source, accidentally opening windows 10 start menu locks up UI
Bug - While dragging a clip from the source window to the timeline, if you accidentally hit the windows key instead of the Alt key, the UI locks up so that you get the mouse cursor that indicates you cannot drop the clip there. Hitting the Esc and clicking around has no effect. All I could do was kill premiere in the task manager. Windows 10 1803 - Premiere Pro Version 13.0 (build 225).
AME was exporting in the background using a lot of the CPU power.
