I've never seen this on ipcamtalk. Only on this one thread, I get a pop-up that requests username and password. As you can see in the top right of the picture, I'm already signed into the forum.
I just tried looking at that thread and got the same sign in prompt. That's happened a few times with other threads as well and I just kind of dismissed it. What was really weird is that I went to post this and this thread wasn't taking any keyboard input. Had to close the tab and reopen IPCT to post this. If that didn't work clearing the cache was next.
Closing the tab didn't fix the login prompt and brought back the no keyboard problem in this thread. I had to close the tab again and reopen it to add this comment.
