[TxMt] latex: typeset & view-problem

dear all,

I just moved to a new machine (from PPC to macintel) and now "typeset & view" doesn't work. more precisely: compilation of the file is fine but preview doesn't work. instead i get a spinning ball in the upper left corner and a paper icon in the middle of the html-window.

on the command line ps2pdf, pdfview etc. do work. if I remove *.dvi, *.ps, *.pdf in the working directory, TM initiates their recreation, so this isn't the problem. it sems to me that, for some reason, TM can't access the previewer.

i re-installed TM, to no avail. same if i create another user account and try it there.

TM, cutting edge.

any hints?

best,

christoph
