tooltip sometimes appears even with 'caption' on

[dadler]

TZP's Show Caption option is supposed to suppress the tooltip (to prevent the tooltip from covering the popup). But it doesn't always work, probably because the tooltip may display before the popup does, and doesn't go away when the popup clears the title attribute.

A solution might be to clear the title attribute immediately instead of when we popup the image, though that may cause more overhead. It'd be better (if possible) to clear the dismiss the tooltip if it's already appeared, but I don't know if that's possible.

This can be seen on deviantart.com, especially if you set "Delay before displaying image" to 1.0 or larger.
