Is there any helpful documentation on the CUI?
I have saved a workspace with locked docked toolbars; when I re-open ACAD, it has reverted to something else.
Also, custom toolbars have lost the icons on buttons.
I am muddling through with trial and error, but it certainly is not as good a process as customization in previous releases ie drag and drop buttons onto toolbars, assign a bitmap to a button, etc.
