I have DisplayFusion v6.0.0 Beta 2 installed, which has it's own optional Alt-Tab handler.
I am running DOpus 11 Beta 7 with the following pertinent File Operations->Progress Indicators options set:
- Display the jobs bar automatically when starting a new job - checked
- Prevent Progress indicators from showing on the Taskbar (or in Alt-Tab) - checked
- Minimize progress indicators - unchecked.
When I am using the OS Alt-Tab handler the progress indicator window does not appear in the Alt-Tab list.
When I am using the Display Fusion Alt-Tab handler the progress indicator window DOES appear in the list.
If Minimize progress indicators is checked (or if I minimize the progress indicator) then it no longer appears in the Alt-Tab list.
DisplayFusion also provides an alternative taskbar - the window does not appear on the taskbar on any monitor.
I have also raised this issues with the DisplayFusion developers - see http://www.displayfusion.com/Discussions/View/alt-tab-issue-with-directory-opus/?ID=74a43f71-8dc4-4628-aecd-aba707c3042b
