Using Unlock All from the dropdown menu doesn't get them all sometimes.
When I want to group some objects I use this feature and lately found sometimes that one of the objects was still locked. Maybe more but I only check the ones I am grouping.
Using Unlock All a second time seems to get all objects unlocked.

Hi Bill,

We have not had any reports of Unlock All not unlocking all objects. If you come across that again I'm sure the development team would appreciate an example .ims project file sent to vmsupport@virtualmechanics.com
