Enable editing of "Hide" timing of subtitles in Subtitle Workshop

[ecc]

I downloaded the most recent version of Subtitle Workshop and the Hide timing is grayed out. The help file says you are able to edit the Hide timing. Is there an option to enable it? I've just been subtracting the time where I want the subtitle to hide and entering the duration into the Duration field or making the changes to the .srt file in Notepad.

On the left you see some settings:

Mode:
Input FPS:
FPS:

Work with:
_ Duration
_ Final Time
_ Both

You must have a check next to "Duration"
If you check "Both" you can edit either final time or duration.

Thanks.
