[h-e-w] Emacs freezes

[Michael Meyer]

Hey guys

I installed emacs according to 
http://www.math.auc.dk/~dethlef/Tips/introduction.html I.e. I installed 
the latest precompiled version of emacs (as described in GNU Emacs FAQ) 
and installed auctex and ispell. Once I open emacs it works well. 
However, after a while the window freezes and the process eats up all my 
memory usage!
How I can solve that problem?

Thanks
Michael
