He was clearly at his wit's end. He asked if I knew anything about this condition. I said sure, don't try to park the ADT Refedit toolbar. In fact, I said "don't ever load the refedit toolbar it is designed to show itself when needed and then hide itself when the routine is ended."
Here is how I fixed his wagon!
Step 1.) Launch the task manager and end the current ADT session. Of course that is easier said than done, because you won't find it in your currently running application list. Use your three finger salute (Ctrl + Alt + Del) to launch the windows task manager, click on the button named "Task Manager". See Graphic for example.
Step 2.) Click on the processes tab and click once on the column heading labelled "Image Name", find Acad.exe in the list, select it and click the "end process" button. Sorry! but you lost all your work in whatever drawing you had open...hopefully it wasn't much. (If anyone knows how to save work while the application isn't visible, please let me know...maybe using vba from excel might do it?...sounds like another article!)
Step 3.) Click Start, Run, and type in "regedit" and click the "Ok" button to launch the registry editor (Insert standard registry editing danger disclaimer...you've heard it before so I won't include it here. You want to fix this problem don't you?)
Step 4.) Drill down inside the HKEY_CURRENT_USER hive to locate the following registry key:
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R16.1\ACAD-304:409\Profiles\Architectural Desktop - Imperial\Toolbars
Change the Red text to match your Release of AutoCAD.
Change the Blue text to match your application (ADT, ABS, LDT)
Change the Green text to match your profile name.
Step 5.) With this key exposed, find the "refedit" toolbar in the list of values on the right and double click it. Now change it from "show" as shown in the next image.
to "hide" as shown in this image.
Now click the ok button to complete the fix.
Step 6.) Remember to never dock the refedit toolbar and you won't run into this one again.
P.S. Another symptom of a docked refedit toolbar is a cursor that flickers uncontrollably when stationary. If you think you are in a disco because your cursor crosshair are more jumpy than a Mexican bean, you probably have a docked refedit toolbar. Hide that toolbar and all will return to normal.
