I have added a PHPSpellCheck button to two TinyMCE editors on the same page. If I use this option to set the fields...
$PHPSpellCheck->Fields = "EDITORS";
...then the spellcheck dialog works, but it checks the text for both editors together. I would like to use this option instead...
$PHPSpellCheck->Fields = "IFRAME:0";
...but when I do that, the spellcheck dialog doesn't seem to initialize correctly and doesn't do anything. See this screenshot:

Does the IFRAME option work for you when used with multiple TinyMCE editors?
I'm using PHPSpellCheck 1.85 and TinyMCE 4.0.16. I tested on my Mac in Safari 7, Safari 8 and Firefox 33 and the problem occurred in all three browsers.
