Comment 43 for bug 239462

Thanks guys. I've tried this out and it works as envisaged.

Whilst I believe the behaviour to be correct in principle, it's easy to nudge the mouse a single pixel whilst reading the tooltip, causing it to vanish prematurely. When I set my mouse to maximum sensitivity, by far the easiest way to read a lengthy tooltip is to position the mouse pointer and let go of the mouse until I've finished reading. This is easy and works reliably. The stop-read-move part comes naturally, but I'm wondering if the "let go of mouse" part will be obvious to some users. Anyone else tried it?

I could live with this as is, but here's another thought by way of improvement:

Would it be feasible to require some small range of mouse movement to pop down the tooltip, larger than a single pixel? Would that be hard to code?

I think this is almost there, but the pop-down mechanism would benefit from a slight tweak.
