Problem with array editor. (possible bug because I am using r155)

My array editor suddenly switched to javascript script and I can't change it back.

Another thing that is happening is that a random window is popping up when trying to open the array editor. My best guess is that the array file was somehow changed it's format to a .json file and now I can't change it back.

Arrays in C3 are stored in JSON format. For some reason the editor doesn't recognize that your JSON is an array. Try changing the array size in that popup window, for example increase array depth. Close/re-open the array, maybe it will revert to table form.

There is 4 bug reports for this issue already. So either use the old version, or wait for next beta.
