I am getting a lot of silverlight crashes lately in DA 3.9.1. I know that the silverlight plugin is prone to errors but loading the same site/page in safari does not generate a crash. Are you seeing this also? Fix please?
Silverlight on the site linked above by the OP, when bookmarked into DEVONthink or accessed through DEVONagent, crashes over here on OS X 10.10.3. Looks like an OS X dynamic loader issue. Silverlight also crashes when that site is loaded into web viewers in Curio and other apps. Maybe you should contact support for the site?
