missing contents of anchored frames

[Miriam Boral]

Hello Everyone,

Periodically, for no apparent reason that I can discern, all the 
contents (either graphics or equations) of anchored frames, both on 
body and reference pages, simply vanish. I can repair the problem by 
copying one of the missing graphics (or equations) from a different 
file and pasting into the appropriate frame. This causes ALL the 
missing graphics (and equations) to reappear.

Although I've found this workaround, I would like to understand why 
this is happening. I'm currently using FrameMaker 7.2 but have been 
having the problem for years with previous versions.

Does anyone else have this problem? Any idea what's going on?

Thanks very much,
Miriam Boral
