After opening some of my RTF’s in an external editor (I have no idea if this is the cause), I came back into Scrivener and typed in full screen mode a bit. After exiting full screen mode, an odd black “highlight” which obscured text appeared. I could move the blackened area around using the cursor, and it would blink as I typed.
(I’ve gotten similar errors in word from time to time, and usually restarting fixes things.)
Restarting did not fix it. However, once I went to options–>editor options and re-applied the settings (note–without making changes), it all disappeared and things are fine again.
Please note that when I am logging bugs, I’m NOT complaining…I love the program.
