Reply To: Mystery of the vanishing text

I very often have an issue whereby the text in a frame does not disappear entirely but suddenly goes pale/grey, almost a ghosting effect. I have to click on the frame with the pointer tool and hold it until it comes back to solid black text, sometimes needing to move the frame slightly before it will come back. This happens on any particular document at frequent intervals. I had not tried the Command-Option-/ but shall in future.
