So I was on Youtube some time today (finding background music for my work) and my mouse randomly locked up, mouse cursor disappeared. I could move my mouse and the cursor would appear outside the page (such as in the browser bar, clicking there) so it's not like it's completely gone. I'm guessing for that reason, not mouse related and this is not happening on other pages. I closed that tab and the same issue was on another Youtube tab - except this time, the persistent mouse cursor finger (the image it shows when mousing over a link) would show on entire page as if page was a link. Again, no issues when mouse was OFF of the Youtube video page. On that page, I didn't have the option to use the scroll bar at the side of the page. Not sure if this was related to my own browser, Youtube, a script running. In fact, the same video page is still up in background repeatedly loadingn videos, no option to scroll up to pause the song on the video, basically i can shut the tab down or just let it keep loading videos.
No stranger to lagging pages/mouse, but this mouse is newer and never seen this on Youtube (though previously some years back, I played an MMORPG game that would seize and lock my mouse cursor in the same way). I feel disconcerted over the situation and don't want to encounter it again.
Possibly it's a one time thing, just reporting it to see if just me or anyone else encounter a similar Youtube mouse glitch situation.
