Are you opening the font with OpenDiskFont() ? This function does not
look for previously loaded fonts in memory, but reload them from disk
every time it is called.

Perhaps you do not see any disk access because you are using AddBuffers,
FaccII, DiskSpeed, or a like ?

I had a problem like that and found the solution into a C= documentation
(don't remember which one, perhaps AmigaMail), here it is:

- Do an OpenFont() to get the previously loaded font in memory
- If successfull, compare the Y size obtained with the one you really
  want, because if you ask Times15 and there is Times24 in memory,
  OpenFont will succes with Times24.
- So if you did not get what you want do an OpenDiskFont()

With this method, the opened font stays in memory, but every time you
run your program it will find it so will not reload it.
