What steps will reproduce the problem? 1. wait for the autoupdater to announce a new version 2. click OK to install - a .zip file unzips leaving a .dmg 3. open dmg 4. copy Vizzy from mounted drive to Applications folder 5. ERROR: cannot replace Vizzy.app, currently in use by .dmg file

You cannot copy the Vizzy.app bundle in the DMG to the applications folder as expected. You have to copy someplace else (ie Desktop) then unmount the dmg and then you can copy to /Applications.

I expect this is because the .dmg update file is contained in /Applications/Vizzy.app bundle

Thanks!

(OS 10.6, upgrading to latest 3.9 version produced this bug)

maybe temp folder would be a better place for storing downloaded update.

fixed in 3.91
