Trouble copying and pasting in ML editor

I am currently working in medialab to create a large file, the file will contain approximately 1024 questions. The format of these questions is very similar. Each is a fill in the blank question with the wording for the question appearing in an html file that is put in the background column. Due to the similar nature of these questions, I have been trying to copy one question to create the other 1000 questions. That way I can more easily create this large file. I have no problem creating the questions. I then save the file (and medialab tells me it saves). However, when I reopen this file only maybe 20% of the file is actually saved. Any cues as to what is happening here would be appreciated.
