I've made quite a few changes to the 1.0.3 version of P2 (borrowing 99% of the code from @jonobr1). Unfortunately, I cannot post of Firefox or Internet Explorer. Safari and Chrome work fine, though.
The exact error message is "Are you sure you want to navigate away from this page? Your comments or posts will be lost if you continue. Press OK to continue, or Cancel to stay on the current page."
I'm curious as to why the difference between browsers and where/how would I correct this issue?
Thank you in advance.
