Bug ID: 41407
           Summary: Cut and paste formatted text from wine to native apps
                    broken since 1.9.18
           Product: Wine
           Version: 1.9.18
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

      Distribution: ---

using wine 1.9.17 and earlier I could cut and paste freely from word2007 into
native apps.
After updating to .18 or .19 I can paste native to wine or wine to wine,  but
not wine to native unless unformatted text (e.g. from wine notepad).
This behaviour is consistent across all the office2007 apps & can be fixed by
downgrading to 1.9.17.
How can I investigate this regression further?
