I have a rpm on my desktop, older sources for a past version of entrance, moot. When I click on the RPM, it seems to restart E or refresh the desktop or efm. The screen blanks, the background shows, and then icons are rendered again. Windows like Terminology and Firefox remain visible thus maybe EFM vs E.
Pretty sure its a bug. I just tried on e 0.21.9 and I got a "Open with" dialog. Not sure if this occurred in alpha, but does in beta. I have not tried latest git.
