When I create a .graffle file on my desktop box and move it to my laptop, any text that was set in Arial reverts to Helvetica. Files created on the laptop and opened on the desktop box are fine.

This occurs only with Arial. Have tried other System and non-System fonts and it works fine. It occurs in files with no stencil or template dependencies. Arial is a little more compact, so this can mess up diagrams with tightly formatted notes.

Both computers are running OSX 10.4.8. Desktop is a G5, the laptop is a Core 2 Duo. I've trashed the preferences, resolved font conflicts, all the usual stuff.

Anyone got an idea what's going on or how to fix this?

Thanks
