Question about max character limit

Hello everybody!

Is there a maximum character limit for mojo regions? I created a site a while back for a client and now they have seem to have hit a limit which is about 64,810 characters of source code (including spaces). when you enter text beyond that limit it either removes it or replaces the last line of code with .

I have tried various things and it is the same in any mojo region and does not seem to be affected by any outside css layout settings. Thank’s You!
