how can I force the tooltip window to be closed?

[Tiemo Hollmann TB]

Hello,

usually the tooltip window closes automatically, when leaving the object. I
have a field with a tooltip, which is located directly to an image, where I
change the tool to a brush when entering the image. Now, when I move the
cursor first over the field with the tooltip, the tooltip appears and move
on directly to the image (there is no gap in between), the cursor changes to
the brush (as wanted), but the tooltip from the field stays open.

That's why I would like to force the tooltip from the field to be closed,
when entering the image. Possible?

Thank you

Tiemo
