I upgraded my wine version to 0.9.9-1 the other day and discovered that some system fonts used by wine for Windows dialogs went missing. The dialogs opened without any text whatsoever in the various GUI objects, including the all-important XLink dialog in my X4 XMetaL installation.

This was very annoying and rendered X4 unusable.

I did some research on Google, without coming up with anything particularly conclusive, so I downgraded to version 0.9.8-1 (winelib had to be downgraded as well, of course, as the library version follows the main package version), and the font problem went away.
