I'm using Zimbra Desktop 1.0.4 (build 1833)

From the 'about zimbra' menu section I can also report the following:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv: Gecko/2008072406 Prism (zdesktop/1.0.4)

Please note: I am NOT starting my browser to go to an url for the zimbra client. I am using the installed application on my laptop, as installed by downloading the zimbra desktop .dmg file.

I am unable to locate where I can undo a default action for attachments.

My example (for clarity): I saved a .ppt file once (and allowed it to be a default action), and now I have no ability to simply open new .ppt files from the zimbra desktop client. Instead, clicking on any new .ppt always results it Zimbra Desktop asking me what directory I should download the file to.

I'm requesting that someone tell me how to undo/re-configure the default action that I've selected.
