Re: Dear Microsoft
That seems to be a loop, cased by the Desktop icon being put on the desktop.
Maybe it's a fringe case, still it allows the user to open an endless number of self-referencing views.
The same thing would happen if one tries to click on - for instance - the network settings on Linux Mint; in this case the app will happily open multiple times. Other Linux flavours / Operating systems prevent this from happening.
This in the end is just lack of polish that has been persisting for more than a decade.
