           Summary: Powerpoint slideshow "unknown error"
           Product: Wine
           Version: 3.0-rc5

                OS: Linux

Im am using Arch Linux. Office 2010 Powerpoint works fine on Wine-2 (various
versions in Arch stable) but with release candidates in wine-3 (rested rc2,
rc3, rc4 and rc5) I get "Unknown error" when showing a slide show in
Powerpoint. Excel and Work work fine and also powerpoint except for the
slideshow.
What information can I submit in order to fix this or am I missing some new
configuration requirement?
Many thanks in advance,
Michael
