Maybe another bug?

Today I worked on wrote program for PRIME which works with saved custom name app variables (Spreadsheet cells) ... Usually I turn PRIME OFF/ON to ensure everything is saved. But when the fireworks begin, I went away(do not know the last state of PRIME, I think it was program editor), until then, everything was OK, in the meantime the PRIME self SLEEPS, and when I return back, when trying to EDIT ANY program (all were listed) or SELECT ANY APP (all were listed), MY PRIME instantly go to black screen and then resets...
So I was forced to delete both - currently edited PROGRAM (first step) and my custom APP (second step) to return my PRIME back to normal conditions... (to be able select any APP and edit any PROGRAM)
