It is very annoying and needs 3-4 selections to go away.....
just to re-appear in a few seconds, that needs 3-4 tries for it to go away.
I gave up on IE several years ago and switched to Google Chrome. No problems here. I did just open Microsoft IE (which I keep fully updated, but don't use) and I received that same message.
Keep in mind that the forum does not support IE. It's plagued with issues, needs constant security patches and is one of the worst browsers out there. Download Chrome (it's free) and give it a try. If you do, you'll thank me!
I use IE and haven't had problems here for a long time.
I have seen that message but never while using this site.
I use that "error message / security warning" as my reminder to clear cookies, delete temporary internet files, etc.
Microsoft officially stopped Supporting Internet Explorer well over a year ago. They announced "end of life" in 2014. The major issue with that is no security updates since 2015. Using IE today is analogous with hiring a $10 streetwalker and not using a condom.
Lots of things on this forum can behave strangely or not function at all with IE.
