Hmmmm. Mine works fine that way. I had this problem once before. I believe the issue is that you have a configuration option in the config file that is no longer supported in your version of Pro. When we went from WF to WF, one of the options changed or was removed, and since we migrated our config file directly, it caused an issue. I can't remember what it was though! My current tree.cfg file looks like this: !Pro/ENGINEER 2002 cfg file Version No. 1 !Pro/ENGINEER TM Wildfire 2.0 (c) 2004 by Parametric Technology Corporation All Rights Reserved. USED_SKETCH OFF SUPPRESSED ON EXCLUDED ON FEATURES ON MFG_OWNER ON NOTES ON BLANKED ON INCOMPLETE ON If you have any options in addition to these, try editing them out. I think maybe it had something to do with the Sketch features. Regards
