Bluetooth mouse won't copy/paste
Bluetooth mouse won't copy and paste using right click (or left). I have checked all the boxes in the mouse utilities are correctly ticked, I have restarted the computer and switched the mouse off and on and still nothing. I can drag text around but not copy and paste from one programme to another. Currently using High Sierra 10.13.6. I have tried clearing it via the activity monitor - no joy either. Keyboard works ok and can carry out copy and paste using mouse via the top line Edit menu. Any ideas gratefully received.
