Trying to run Preview 1.11 starts a "must download new version" which fails.
It fails with a suggestion that there might be a problem with an anti-virus program or firewall blocking the download.
1.11 has been removed from the title of this forum and from the download site.
If the reason the download fails is because their is no file to download then the error message should say just that.
Does this mean we are stuck with the current snapshot system and enter key weirdness an so on till 1.12?
