Mising Fonts and Conversion

[Oldfogey]

Don't be surprised if you see bloodstains, broken (monitor) glass and tears on this post.

Some time back and elsewhere, I asked if anyone knew how and why my customer's (and my) Helvetica just up and went. Nobody knew. We've been slowly converting to Arial and now I find there is a bug in converting Arial from V6 to V7!

We still have dozens of layouts with ex-Helvetica on them. If you've struck anything similar, you'll know that this shows as a blank font box in layout mode.

The question. Has anyone out there converted a layout with a non-font to V7? If so, what happened? (I can check on Developer's behaviour but not vanilla V7.)
