THe only weird thing I've noticed from Steam as of recent is whenever I click a link / load a file from the community page / store page. It at times doesn't register it as me clicking. I submit something and at times it just doesn't click it. I have to reload the page to click anything. It's weird but it's been happening.
That happens with me as well since a long while ago. I have seen others with the same problem - along with a wonky page scrolling - but IDK why they haven't fixed it. What I do is click the search box again and click the game until it enters. Mostly it happens with the small search list.
