I would shutdown the program, then delete the contents of the "Built-in" folder. Restart TurboCAD and see if you can now move your toolbars without crashing. The "Built-in" folder is normally "Hidden" by Windows, so you may need to go to "Tools / Folder Options ↠ View" page in Windows Explorer to reveal it. When TurboCAD is restarted, it will rebuild most of these files and rebuild the rest when it is shut down.
In Vista/Win7, the folder is located at: C:\Users\your user name\AppData\Roaming\IMSIDesign\TurboCAD\16\Professional\Profiles\Built-in
