It depends on how you enter the Script Editor.
Since the Script Editor is now modal - allowing you to flip in and out without having to close the Editor, an OK button doesn't make sense.
In other instances such as modifying a script via the Button Setup dialog, which isn't modal, you need the OK button.
It takes a little getting used to, its a matter of context. This was the case in FM 11 as well.
indats may be behind the curve,
Its been that way for a long time. It changed when FMP started using a modal window for script editing.
In the first image series you are just editing a script. That requires a SAVE (command-s) when you are done editing the script. In this window you can select other windows and perform other editing operations.
In the second image series you are assigning a script to a button and then editing the script. The method of entry places the Script edit into a non-modal window. You can't click out of it to do anything else so it requires an OK to complete, not a Save.
P.S. Regarding the spellcheck question - in the top right hand of the box which you write your post in, you will see an 'abc' and a big green tick. Hit that to have your post spell checked prior to posting, unfortunately it doesn't work on-the-fly. All the best, Ben
I have noticed the issue for some time, and your explanations certainly make sense, as to why it happens, although it still would still be helpful if they included a button to save or cancel your work, I guess I will need to add Ctrl-S to my keystrokes.
Ben, Super Thanks, I guess I need to get more familiar with the forums
