When I enter an accented Spanish character (á é í ó ú ñ etc.) in the table as target, the next character I type causes the accented character to disappear. Plus there's a ghost effect where two or three characters show faintly under the text.
What can be done with the intrusive Preview? I close it, it goes away. Then I enter a single change in the table and it pops right back at me. It should respect its last state! It takes away half of my window.

thank zou for contacting us.
Can you please specify how are you inserting these characters? There are several input methods and we would like to capture all the possibilities. Nevertheless, our technicians are already working on a fix for this problem.
As for the preview, you can completely disable it in Tools menu.
