Sometimes cannot change readonly mode.

[Anonymous]

I use Fusion360 all the time, but now that the edit/readonly mode is enabled, it mostly doesn't work.  Sometimes I am able to click the "editable" option in Fusion and it works... the next day I will load the same model on the same computer, and it won't let me edit my own files.  This is terrible design and has hindered my productivity since it has been released.  If I close and reopen the application many times, it sometimes starts working.
