DEVONthink and Mac OS X 10.6.1's Mail.app
Just a quick note that Mac OS X 10.6.1 again breaks compatibility with the earliert version of the Mail.app plug-in. You may should know that Apple Mail does not support third-party plugins at all so what we did is basically a hack (one reason we did not make a plug-in for Safari but a bookmarklet). The solution is simple: choose Help > Install Add-ons… and re-install the Mail.app plug-in to update it. This installs a newer version of the plug-in which will happily work with 10.6.1.
