Can someone explain why the text and leaders placed over viewports (in paperspace) keeps disappearing? The text is still there...just not visible. i can select the text with no problem. and if i move it off of the viewport then i can see it just fine. this is happening with all the viewports in my drawings... on all tabs. If i close the drawing and reopen then all the text appears again.....but when i switch tabs then come back...the text vanishes again.
