Not only all my dashes disappear when I import an RTF file from Word, the 3 full stops disappear also.
Examples:
“Did you ever …” (Word)
“Did you ever” (as imported in Scrivener)
“Did you ever –” (Word)
“Did you ever” (Scrivener)
Because I use this very often in my novels it has to work properly.
I can’t duplicate this bug in beta 1.55 on Windows Vista Home Premium
Do you have any more info?
If you create a new document and “type test test test…” , and try and import that is the bug still there?
PS. The pedant in me wants to point out tyhat the “three dots” are called ellipses 
Thank you for reporting this.
The ellipses have been fixed in 1.55, however, em and en dashes have been fixed in 1.6 which has not been released as yet - due in a week.
