Sounds like a simple question

I have a question. In working on configurations here and there, I was wondering something. In some cases I have been relegated to using PCF files and not knowing why I just go along the way "they" want. I have had to make my own tweaks in my ucf to get things working right (for me). But I recently had to fix a configuration that was looking for ms_fontpath but it could not be found so Microstation exited. I looked at the users ucf and saw that it had a specific font path set so I commented it out and things worked as expected. BTW, this was happening on a different computer. Anyway, the user (and myself) wonders why his ucf works fine on his computer with the font path uncommented.

Any information is welcome

Thank you
