[NTG-context] Problem with MkIV and tikz

Hi, I've got yet another problem with ConTeXt... I was using MkII and \usemodule[tikz]. Everything went smoothly until I tried MkIV; it can't find the tikz module. What I did was: 1. I installed the ConTeXt minimals. 2. I downloaded pgf from sourceforge and unpacked it somewhere in the context tree. 3. I ran texhash so that the file database got rebuilt. 4. For MkII, this was enough. 5. But then, I wanted to use an earlier advice on fonts in MkIV and switched to platino (=pagella). 6. Although pagella works fine, ConTeXt no longer finds the tikz module. Does anyone have any idea what I am doing wrong? -- Marcin Borkowski (http://mbork.faculty.fmcs.amu.edu.pl)
