Hi all, When writing a mathematical text I encountered a few problems with bold symbols. Under the line you will find three problems (dutch interface). Are they due to my insufficient knowledge of installing fonts? Thanks for any comment.

Problem 2: ${{\bfm \beta}}$ gives a wrong glyph (in fact the ligature 'fi'). Problem 3: After $\bfm \beta$ the text is no longer printed in the same Lucida Bright style as before. \stoptekst
