Microsoft Edge has worked well for me since my Windows 10 upgrade last September. For the past three days, however, my internet browsing experience has been horrendous. Edge frequently stalls, with annoyingly long delays in responding to mouse wheel (scrolling) activity. The spinning blue circle that comes on during these interruptions reminds me of the nightmare I suffered through with Windows Vista years ago. Thinking that viruses or other contamination may be the cause, I ran my McAfee security suite (sponsored by my ISP), but the results showed no sign of contamination.
Can anyone help?
