My problem appears to be resolved but I am stumped on why.
I have applied all the suggested "fixes" in the past 18 months or so to no avail. When the comments were made about USB v Wifi, I was intrigued about that.
My pc is a "directly" connected RS232 via USB dongle. PCs don't seem to have those RS232 ports anymore. I experimented and turned on Wifi on my pc and using Wifi the problem disappeared! Technically, I am using a USB port but want the direct connect to internet. My pc is too far from the router to get good response via Wifi and why would I use a USB connection when I want good response.
I then turned off Wifi on my pc and the problem is no longer appearing.
Huh?
