I find this extremely annoying too, particularly when I am attempting to copy text, unfortunately I wasn't able to find any permanent fix.

The best solution I have found is simply pressing the [Alt] key to close the tooltip window. Doing this allows me to view/click the text without the tooltip popping up again. Technically all this is doing is highlighting the file level menus instead of the editor view but it is effective because it is refocussing the cursor.
