Just loaded the new DP 8.0 Beta 8 and noticed that Display Fusion no longer appears in the list of Notification area icons that you can select from when right-clicking the main window taskbar / selecting Properties / Pressing the 'Notification area Customize' button and finally selecting 'Select which icons appear on the taskbar'. In all previous releases there was an entry for Display Fusion where you could turn the icon On or Off. It is not there in this latest release. The icon does, by default, appear in the Notification Area.

Using Windows 10, 64-bit, latest update.

Yes, uninstalling and reinstalling Display Fusion cleared up this problem. The previous install was via the prompt that Display Fusion gave me advising me of an available update and using that method to update from Beta 7 to Beta 8.

Issue closed.
