Spark community website preview is outside screen

Hi,

Not really a spark issue but one with the spark website. Hope it is at the right place here.

On my browser (Mozilla 18.0.1 on Windows 7) the preview of the Spark community forum, when writing a new post, is mostly outside the browser window. You only see about two lines off it at the bottom right of the windows. So you cannot really see your post.

Same thing happens if you draw down your input area so that in begins to show a scroll bar. This lower part of the scroll bar is also outside the browser window.

And the “New Topic” and “Cancel” buttows overlap your writing.

Does anyone experiece the same weird behaviour? Is it a website bug or a browser bug?
