the "switch to full box" doesn't work  

 

Twice now on different posts, I've started entering text in the quick response dialog box, but when switching to full dialog, all of what I've written has been lost. Even when trying to go back to previous screen, all is wiped. Never was that way before, a recent event. I've been responding to specific error questions, then realize I need to add some pix info....quite distressing to have to rewrite half a page of text!
