Recently I have started having this annoying problem where I select something and it shows it is selected by the grip but in reality it hasn't selected it as can be seen in the properties box.
Cancelling the selection with the ESC key doesn't work
regen doesnt' work
regenall doesn't work
audit doesn't find anything
Qsave does work but I would prefer not to use it due to sharing drawing xrefs with others means that they constantly have to keep reloading the xrefs
Have tried reinstalling autocad but that doesn't make it work.
Was wondering if it may be something to do with the graphics? - Currently have a NVIDIA Quadrow 3500 which is probably not the correct one.
This behavior can be caused by running a Windows registry cleaner. They do not work properly when you have AutoCAD installed. To fix you go to control panel, add/remove programs and select the repair option for AutoCAD.
Read your 1st reply, the cause of it is the registry cleaner. Nothing you can run now that will fix the problem except repair or reinstall autocad.

Certain anti-virus do it as it said here:
