[Constraints Palette Won't Stay Put in 12.5.]

I'm having a couple of similar problems with my recently upgraded 12.5. My workspaces won't 'stick' either. Everytime I re-open the program I have to re-select the workspace I was working in before. Additionally, although I'm not sure this is related, every time I try to use the "Fit Walls to Roof" command the program freezes/crashes. Just a little annoying. Anyone experiencing similar things?

[12.5 Update killed Vectorworks]

While we're about it, I'm unable to install VW12.5 at all. The installer and file extracter crash just as the installation process is finishing. I tried it 4 times before finally giving up. Anybody else experiencing this? Any advice?

[Plotter/VW12/OS10 Compatibility]

I'm running VW12 on a brand new MacBook Pro (Intel) on OS 10.4.6 and I'm suddenly having a lot of problems printing to a Cannon iR2200 printer that we use in the office. I say suddenly because I have printed before from this computer with this software to this printer. Now all of a sudden the program will not recognize any paper size besides 8.5x11. Has anybody else experienced something similar? Anyone know of any fixes?
