Hi.
Sorry if this is already a known bug.
I have three folder portals, two showing Classic Icons and one showing Details. When I open an application, the portal in Details view will draw over applications on the screen. Also the desktop will become the active application so I have to wait for the application to load and then remember to make it active before doing any work. See the screenshot ... it's clearly being drawn over the application on the right, but you can also see the column dividers drawing over the aplication on the bottom.
Also while using the application, the desktop will randomly become the active application again. This is an issue if I were to be pressing the delete key in the application for example, then it will delete whatever icon is selected on the desktop! Fortunately that's only happened once but now I have to remember to check the Recycle Bin for things that shouldn't have been deleted! Most of the time I'm just typing and then I press Enter and it opens whatever icon is selected on the desktop, still annoying!
This is on Win 10 x64 2004. I remember it also happened on 1910 but wasn't so much of an issue because it was only drawing over applications, and wasn't making the desktop randomly active. It's just become a bigger issue in 2004 due to deleting icons.
I've tried recreating the portal but this doesn't change anything.
