Ok, now it's just pissing me off... Everytime while I am in the explorer, handling files, preferably with the right-click the stupid context menu is just disappearing. Like not everytime, but often enough to get me to hate it! I just have to mark multiple files or folders, try to right-click it and boom! Magic happens. It disappears. Works on the second time most of the time though. I have a feeling that I am way too fast for the explorer. It seems to be not of a problem if I mark multiple files, wait a second or so and then try to open the context menu. But I work with multiple files everyday and it's killing me. No problems while I am on the desktop or something. It even doesn't matter which file it is. And if my memory is correct it even happened with 8.1 after a while. Something is definitely wrong with this s**t. Doesn't matter if clean install or not. Tried it on another computer in the house. Same problem.
