I have not tried this on 2003 yet, seemed to work on SolidWorks 2001 Plus.
Tool Bars
SolidWorks 2003 enables certain Toolbars, depending on the type of file (part, assembly, drawing) that you are working with. This feature was intended to minimize the number of toolbars on the screen, and eliminates the Toolbars that cannot be used for a specific file type.
To turn off this feature, select Tools/Customize/Toolbars and uncheck "auto-activate sketch toolbars." This should keep your Toolbars displayed where you want them. It seems that you have to do this once for each type of file (prt, drw, asm) you open for the first item.
