The callout tool is giving me problems in one of my vectorworks 2010 files. Anytime I try to edit the properties of this tool it crashes, any time I try and edit the text it crashes, and many time when I am creating a new callout it crashes or if not I get the spinning pinwheel for a length of time. This file if contains a very important project and it would be impossible to recreate it. Please help!!! I'm on a 3.06 iMac with 4Gb of ram running OS X 10.5.7 James
