This is probably posted in other forums, because I don't think the problem was specific to Quicken 2007. I had installed it under Crossover Standard, and it was working fine -- then suddenly today the fonts were all invisible. After much digging around, I found this blog entry, which explained that it was due to an nvidia driver problem.

This fix was to put this text into ~/.cxoffice/win2000/drive_c/reghack.txt:
[HKEY_CURRENT_USER\Software\Wine\X11 Driver]
"CLientSideWithRender"="N"
Then I went to Applications | Crossover | Run Windows Command, and ran
regedit "/home/<myname>/.cxoffice/win2000/drive_c/reghack.txt"
Fixed!
cheers,
