Just a tiny bug so far: ?>

Hi there!

I’ve recently managed to get your plugin, but there are two things that concern me:

First, after turning on, wordpress informs, that plugin calls 2 unexpected “headers already sent” errors, but I don’t see any further trouble with it.

Second one: plugin added ?> to the top of my blog, and admin area (just over the left menu). Should I worry?
