I have a dual monitor setup and I maximize acad2011 on monitor 2 and have my toolbars on monitor 1.
I like to have my toolbars floating, but justified to the side with the 'gap' between the montiors so the tool bars fly out and I can see my email or reference docs or whatever on monitor 1 also. Sadly every time I close and re-open acad my toolbars re-justify to the center of monitor 1. I've tried unlocking and locking but that doesn't work. I am using the 'better', errr, excuse me, 'classic' workspace.
I tried that earlier, no joy. I've tried saving it to acad classic and to my own name.
Just some further info: When I config my toolbars they're set to not allow docking, and they fly out away from the acad window. Dunno if that makes a dif.
We're on subscription so maybe I should just upgrade to 2012.
Does your AutoCAD load an external Profile or add-on at startup?
Are you using plain AutOCAD, or a vertical "running as AutoCAD"?
Locking toolbars is to prevent you from accidentally moving them, it's not a substitute to a saved workspace: so something is resetting your workspace.
I use vanilla acad. I notice that while my named profile loads by default and has a check next to it, when I select again from the bottom bar workspace switching flyout it DOES correctly position the toolbars.
It's not a fix, but an acceptable substitute and yet another thing to remember to do in the morning.
But you shouldn't have to really. I have two monitors on two different setups, both using NVidea display drivers. Both have the display setting to span both monitors. This allows me to place different programs on either of the monitors or maximize the screen of one program to span both. I've only recently started Anchoring palettes on one side of the screen, but for many years I left several floating (but minimized most of the time) on the second monitor. By saving and naming my custom workspace they never had to be adjusted once I set them. I would manually move things now and then, but they never changed on their own.
This is a long way of saying the problem might be your display card settings, and not something in AutoCAD.
