Hi Jim,
Vectorworks is a great program. It's clear that patches take time and can't be released the day after the problem occurs. What's annoying is that service select users feel misused as beta-testers, trying to run a programme that is announced as "ready to work", loosing lots of time with crashes and testing. If VW 2016 were released as "test it out, but we will call it a stable version a few months later" everyone had known what to expect and no one would be disappointed.
So as always, its mainly a matter of communication.
Meanwhile I have set the GDI handles to 100,000 or so, which results in a halfway stable version, but the delay when changing layers or classes is still there.
So I'll be patient and wait for SP2.
