Sebastian,
Try -drop _all- instead of -clear-. As you suspected, -clear- closes postfiles.
Note: -postutil dir- lists open postfiles, useful for showing what's happened.

Subject: st: Postfile "forgets" the postfile
...the typing error (using y instead of x) is not responsible... i
just saw it in the post, but in my do-file, i surely used the exact
same name all the times i referred to the postfile (i also changed it
several times, so its not because of some specially "bad" name).
thx for helping me out!
