Thank you for your response Benson! Here is some more info:
I do experience the hesitation, some objects hiding for a moment, and some objects disappearing when I zoom in too far. These are things that we all probably experience... I just accept them as part of "pushing the limits".
What we are puzzled by in our office is the consistency of the freeze/crash on these different machines (desk and laptops- all macs- all running the same version of Vectorworks and OSX). It freezes mostly when we use the scroll on the mouse (we have several different mice including the tracking pad on the lap) and when one uses the zoom tool (little magnifying glass) but not during a command 4 (see page) or command 6 (see all selected/drawn). I am not familiar with other zooms. We can not recreate the problem when we turn off Quartz Imaging & Anti-Aliasing in the VW Preference Window (but working without smooth lines, text, and transparency really stinks).
VW is the only program that stops functioning and a force quit and application restart seems to get things going again, until another freeze. I saw the SketchUp post and found that very interesting, and considered other devices/programs as possible issues. However, my home laptop is not connected to work in any way and does not have other similar programs.
So I did a little test again that went like this...
- Opened a new blank file. Added a jpeg image. No Problem!
- Added some of the common fonts in our files. No Problem!
- Tried to add our Custom Title Block, and it froze.
- Opened an existing file and deleted the Title Block. No Problem!
So I think I have found the culprit, but how it is related to Quartz Imaging I don't know? And why it worked when used on OSX 10.5 I don't know either? And remaking all our files and title blocks for countless sheets and projects makes me nauseous. I have a blank file w/ a custom title block to attach that maybe someone could try, but I am not sure how to attach it?
