Right Arrow-key bug in file naming during 'Export to PDF' in Output Module

I'm having a consistent problem when renaming a file name or just editing it in the file name field in the Export to PDF dialog window.

When I have the cursor in the file name field, and use the right arrow key to move one character to the right, it performs a Cancel action and the Window disappeas, and I have to start all over again.

This happens every single time, this is a very annoying bug that should be fixed immediately.
