[Zope] ZMI Editor Corruption

[Dan Shafer]

I edit my Zope sites primarily on my OS X system, occasionally using Win2k.

Yesterday, I began noticing some unusual crud showing up in the Python 
script files I was working with on OS X. The first thing I noted was that 
the first few characters of the first line of a script had just 
disappeared. I went to a text file copy of the script on my local drive and 
copied the missing characters, went back to Zope and pasted them.

Instead of the pasted characters showing up, I'd see several unprintable 
characters. You know, little rectangles, symbols, etc.

I must have spent 15 minutes with the stupid thing trying to isolate the 
problem. I even re-copied the entire script and pasted it. It never got any 
better.

Finally, I deleted the script, created a new object of the same name, and 
then pasted in the file on my disk. That appears to have worked.

Is this documented behavior? Is my data.fs file perhaps corrupt? Any insights?
