I do not know what I have accidentally pressed, but suddenly I have a little blue square at the end of any line that I have selected.  There is also a funny symbol with 2 parallel lines and some diagonal hatching which appears near the blue square.I believe these are a grip symbols, but they now persists even when I go on to do something else and I find it really annoying to have them cluttering up the screen.Can anyone advise how to get rid of these and make sure they do not appear again?I right clicked on the screen, selected Options > Selection > Untick Show grips and all the boxes below this.  > Apply > OK but they are still there. I am running Win 7, Autocad 11.Thanks,Arthur

Hello ArtM101, all this looks like parametric constrain.To get rid of this you should DELCONSTRAINT , all.Eventually see this :https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/AutoCAD-Core/files/GUID-E47B6F79-C7DA-45ED-AFA6-6C0945DB6375-htm.html

and if preferred you can turn of the "Grips" with the Grip system variable.Grip0=hide1=display2=display additional midpoint grips on polyline segments https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/AutoCAD-Core/files/GUID-97AD30F3-A1A3-4027-91B7-49008841A447-htm.html?st=grip%20variable
