I lost my docking guides quite some time ago and I can't figure out how to get them back.

Initially, I thought maybe it was an OS (Windows 7) configuration but my visual studio docking guides work correctly.

I can still dock, but it's the old style of docking (no docking guides).

ArcGIS 10 SP2 in Windows 7, x64

Viewing Multiple Tables

Can you clarify what a docking guide is? The little 4 arrow graphic that lets you decide where to snap the window to? – MLowry Aug 9 '11 at 19:47
That's correct. The 4 arrow graphic with the "tab' option in the center. It was the only good thing about ArcGIS 10 (just kidding...but it is one of my favorite things about ArcGIS 10). – Jay Cummins Aug 9 '11 at 22:20
Are you sure you don't have the little pushpin in the auto-hide mode? I assume you've tried a restart and repair ArcMap installation already. – MLowry Aug 10 '11 at 15:40
Restart: Yes. Repair: No I have no reason to assume anything is broken, just that I don't know how to get it back (which is why I posted the question). ArcCatalog does show the docking guides. – Jay Cummins Aug 10 '11 at 16:08
Since normally holding the ctrl key down while dragging causes the guides to disappear, I wonder what would happen if you did this on a machine where the guides are not visible to begin with. – Kirk Kuykendall Aug 10 '11 at 19:13

I deleted the HKCU\Software\ESRI\Desktop10.0\ArcMap key and restarted ArcMap. Docking guides are back!

I'm not sure what the precise setting is since I accidentally deleted my original ArcMap key during troubleshooting. But it wasn't DockingPaneLayouts (which was the first one I tried).

Awesome! Glad you got it figured out! – MLowry Aug 11 '11 at 12:30
