Just for the record: the above mentioned hand also sometimes happens 
when typing V ... E ... R ... Y ... slowly ;). It is just more frequent 
when typing faster (mainly because a hang only ever happens directly 
after having pressed a key).

Yes please. How can I be of assistance (as apparently the only person 
having this kind of issue ;) ... maybe I should just buy a new computer, 
however, Fedora Linux is my preferred Platform, so maybe as soon as I 
get my hands on a different machine having Fedora installed -- which 
might take some time -- I should check whether this is specific to *my* 
laptop or a general issue of Fedora; or did we establish an answer already)?
