Every once in a while the tooltips start showing up behind the taskbar so they can’t be seen. This is very annoying.
I found a fix that worked, but I’m surprised and a little dismayed that it fixes the problem. It’s like telling someone with a headache to jump around clucking like a chicken, but hey, whatever works.
The way to fix the problem (thanks to Kelly Theriot) is as follows:
Go to Start/All Programs: Hover over any program listed, right click and select Sort by Name. Repeat once more.
I sorted by name once and checked the tooltips and they still weren’t visible, so I did it again and it worked. It remains a mystery why this has any affect on the tooltips being visible, especially having to do it twice.
Update: Thanks to several commentors for pointing out ToolTipFixer, a free utility (requires .NET) that solves the tool tip problem once and for all. Another solution is to use nircmd as follows:
nircmd win settopmost class "tooltips_class32" 1
