Thanks for the input Ken, and apologies for tardy response.
I have to say that after suspicious/unfriendly AV suites, my thoughts turned to Safari (Apple users have my undying sympathy
)
At one stage of my testing, on my IBM compat, I tried the Windows compliant Safari (5.1.7) but it wouldn't let me access the site at all. Zero progress.
For what it's worth:
i7 930 3.2Ghz (older than its owner)
12GB RAM
512GB SSD
6 TB SATA3 6GBs Archive storage
GTX460 GPU (same age as processor above)
Win 10 20H2
50Mbps NBN (currently downloading @60Mbps !!!)
Cheers
