buttons below visible area

["Johannes Hüsing" <tmi0m0@spi.power.uni-essen.de>]

Another problem I am experiencing:

When compiling the following source text, the defined menu which should be
at the bottom of the page is off the page. If I set the height to value
3\bottomheight, the buttons are cut off at the bottom, but at last readable.

Any idea what I am doing wrong?

Thanks 

Johannes

Just to type out some text which is unimportant. The bottom of the screen counts.
