I had different freezes on using Groovy code and file extensions like xslt and large files. Everytime I lost my code changes. Up the momet a collegue of mine searched for it and told me there is an autosave in ReadyAPI!
*-/7eçà'* - stupid me!! §'3(çz$^- Hey my bad, but I think it would be good to put the autosave by default on 1 minute. If someone don't want all that saving, he/she can still change it. In my case this is a very enlighted solution.
