--- Comment #10 from Aric Stewart aric@codeweavers.com 2012-01-31 10:26:32 CST --- Might be a duplicate, however.
The reason you saw the change was that for a while uniscribe in the edit control was always falling back to Microsoft Sans Serif for fonts, that is not the right behavior and it is correct that your font linking for Tahoma is incorrect.
could you generate a +font log for me
also look in you ~/.wine/system.reg and copy out the contexts of your [Software\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink] key
thanks! -aric
