Selecting a file works fine, but direct text input is very awkward, for example:
- I can't paste text with the middle mouse button. Ctrl+V and Right button -> Paste does work.
- If I start writing the name of the file an there's a file that matches the begining of my input, an autocompletion box will appear, and when it does I lose the ability to keep entering my input. If I press ESC, I can enter another character, but then again the autocompletion box appears and I can't keep writing.
- Deleting text with the backspace works, but pressing the "Clear" button on the right doesn't. Right button -> Clear does work.
