Hi Trygve,

I'm pretty sure that the setting that is causing this behaviour is found under "Options | Preferences | Arrange". I've highlighted it on the image below.

Disable the checkbox for automatically substituting ZZJAZZ.STY if a style is not found and see what happens.

Why it opens correctly sometimes and not other times could be due to how you are starting BIAB.

For example... Do you sometimes open the file by double-clicking on it and sometimes open it using BIAB's "Open" command? If so, it might be that the double-clicking is opening BIAB from another location and the PNO34-12.STY is not present at that location.

Regards,
Noel
