Opened Rhino v4 and found Layers Panel moved from right side of the 4 view ports to the top of them below tool bars. Seems to be locked in place and no way to move it back to the right side. It won’t drag like the Properties Panel.
Put your mouse pointer over the two thin double lines on the left end of the docked panel.
Left-click and hold, drag the panel off the edge of the application window.
Pops up above 4 viewports as shown in screen shot above. Closed and opened Layers Panel dozens of times. Always comes up in same position. Always locked from dragging. Properties Panel drags as is normal.
Geez, sounds bizarre. I know there is a registry entry for the various window positions that you could probably reset, but as I don’t have V4 installed anymore, I can’t tell you where it would be.
Close Rhino, run Regedit, and try deleting this ley:
HKCU\SOFTWARE\McNeel\Rhinoceros\4.0\Scheme: Default\Window Positions\Docking Windows\Dock bars\2363ed67-616d-4861-9e87-e2f38fe788a5
Restart Rhino As Administrator and the missing key should be replaced with default settings.
