Question: Can't resize any window. Handle is there but no good

Out of the blue my iMac windows have suddenly become unchangeable? No matter what program I'm running i simple cannot change the window size or move it?? Really weird? I did try looking at a different display in System Preference a few days ago, but put it back where it was. I've run a Malware detection software and First Aid in Disk utility but so far no good.
Any other tips? Thanks

Try setting up another admin user account to see if the same problem continues. Also try the Safe Mode.
