Woooooooooops!
The notification e-mails from ENWorld stopped showing up, so I assumed the thread was dead. My bad!
Gods, I'm gonna have to work back through the thread to find things to respond to, but for now:
Re: brehobit's issues with Firefox
Not sure why he's having problems. P2 has been tested with FF 3.6 and 4.0, but not with anything older than that. Also, he might have some addon installed in Firefox that's blocking part or all of P2 from working.
Re: "Invalid Markup"
A number of monsters on the Compendium contain invalid XHTML (some tags are left open). Web browsers are designed to handle these errors gracefully, but it makes the XML parser that P2 uses barf all over itself. P2 tries to fix invalid markup when it encounters it (this happens a lot more often than you think) but it still breaks sometimes. A list of offending cards would be useful, though (PM me the name of the monster, or e-mail me).
Re: Any problems people might be having with the printing interface
These bugs have been really hard to fix, since I can't seem to replicate them on my machine. I've added a "Not working?" link on the top left that will e-mail me a set of diagnostics if you click on it.
Re: Monster level slider
Most definitely! I don't have a copy of the Dungeon Master's Kit (which I believe has the most recent level-adjustment rules), which I've been meaning to buy. My local game store never seems to stock the damn thing.
