If the browser's window is not large enough, the PostTo's popup box can draw offscreen. This can potentially hide both the commit button and the cancel button. Since the popup box attempts to stay centered, scrolling has no affect on letting the user get to both buttons. Their only alternative is to assume its broken and refresh the page.

We have a fix for this in for our next roll. It fixes the problem with smaller screens but introduces another small issue where the user may sometimes need to scroll up to view the entire PostTo overlay - we're working on making a more elegant solution but wanted to get you something so that PostTo is accessible to all.

thanks for the bug report - keep'm coming!
