--- Comment #19 from David Brooke <david2012bro...@gmail.com> --- Per your request I have provided the following information to better clarify the main issue. I have created three short videos: Expected correct condition (which shows the group popup): https://dl.dropboxusercontent.com/u/17574275/group-popup.mp4 Error condition - hidden panel (C3770-P2): https://dl.dropboxusercontent.com/u/17574275/TMWP-5.8-neon-C3770-P2-1.mp4 Error condition - group popup (C4790K-P1): https://dl.dropboxusercontent.com/u/17574275/TMWP-5.8-neon-C4790K-P1-1.mp4 Error conditions: The hidden panel cannot be accessed or if it can, the wine program (Sierra Chart) task button does not have a group popup showing the available windows. In either instance a transparent outline of the panel or the group popup is displayed and other windows cannot be brought into focus while in this error condition. Error correction: Switching to another virtual desktop and moving the mouse over then away from the panel seems to correct the problem condition. You can decide whether to conquer both error conditions or separate them into two different bugs. I lean toward that both originate from the same issue but manifest slightly different results. Note: Both test computers are very similar but the video capability difference stands out to me as a possible key element.
