Viewport manipulation is very slow in V6 WIP if I have two or more files open. I could even get it to crash by pressing and holding “home” (UndoViewChange). I did send the crash dump. Happens on both my MacBook and iMac.
Same problem in the release version of V6 Windows if you have two files open as a worksession… Rhino freezes, but no crash dump.
Are you able to repeat these problems?
