doncha hate it when --

-- you have a folder open in explorer, and you type a couple letters to quickly move down the folder to access a subfolder in the directory - like "fi" for "fiction" in my documents - and the cursor is already below the pt where that folder is, so instead of the folder, you have landed on a pdf or something worse like a photoshop file, and by then, you have already hit enter, so it opens & takes forever to launch.

-- you go to copy some files, and mark them all, and then instead of copying, you click one too many times, and open them all, and have to close them all before you can copy them.

-- you go to delete a file, and hit enter too quickly before the "are you sure" question comes up, and then the enter is taken as a "launch the file" instruction, and the file tries to launch while it is deleting, resulting in an error message.

-- you go to a webpage, and click on the page to activate the window so that you can scroll down, but the webpage is secretly loading a popup which intercepts your click sending you somewhere else.
