If I click "New Profile" or "Edit Profile" in the launcher, I cannot close the window that comes up. Clicking cancel or pressing the window close key combination will cause the window to disappear, but the window name is still present in the taskbar. Moving to another desktop and back causes the window to reappear, but all elements on it are unresponsive to inputs.

Closing the main launcher window cleans up all of the frozen extra windows.
