I wrote this up on FM 7.0. I assume it'll work on 7.2, but havn't tested it on 7.2.
There's an issue in the 6.0.0 release with all the fonts disappearing the second (and all subsequent) run of Framemaker 7.0. Codeweavers is aware of it. To get it to work, you can delete a .ini file that happens to let initialize correctly. The path below is for Framemaker installed in a "win98" bottle for a user install - you'll have to modify appropriately if your setup is different
~/.cxoffice/win98/drive_c/windows/profiles/crossover/Application\ Data/Adobe/FrameMaker/7.0/maker.ini
I've got a script file that deletes it that I execute before running FM. Good luck.
