[NTG-context] MKIV and path updated by Mktexlsr...

Hello list, I do not know why, but somehow ConTeXt MKIV stopped (in texlive 2010) look up the my .tex files (my libraries) that I placed to c:/texlive/texmf-local/tex/... etc. .. While MKII works fine. Is Mktexlsr command for MKIV without effect? Knows anyone what may be the problem and how to fix it?? Thanks Jaroslav
