--- Comment #22 from tormen tormen@diplomail.ch --- Hi,
I recompiled wine 3.9-1 on Archlinux using -O1 and this seems to fix the problem, for me. (5mb bigger wine package ;))
Whereas the WINEDEBUG=relay seemed to fix the problem: MSO setup started (on first run of MS Word after fresh installation), but followed by this MS Word ran again into the bug #45276 !!
