The application is not saving the script I write "Edit -> On Load". 

I had some code entered in the above mentioned section, when looking at it earlier I noticed that half if the code I had written out is missing. Luckily I had saved it somewhere else, however when I paste the code and tell it to save the script it doesn't save it. It give the notification "saving.." then "saved", but if I switch to another view and back, the code snippet disappears again.

This is the second time that this has occurred. Last time eventually it allowed it to save. But I really don't understand why it's deleting code in the first place.
