Hi Walt,
Thanks for your reply. Yes I've seen that Nahimic is running. (You can tell I'm not a techie, ha!)
I've just run it with those parameters and I don't seem to be experiencing the issue any more!
I saw earlier in that thread some discussions about which drivers might be causing the issues etc. I've managed to notice the issue occasionally in 1Password and OCCT (computer monitoring software) as well.
Thank you for your help!
@SPaceBar seems to be solved, but also a thickened plot by the sounds of it?
I definitely no-where near savvy enough to know how to roll-back particular drivers and updates etc.
