Re: Sliders and MouseDown

Hi Steve,

Pressing ESC may not be an option for some pointer users, and I don't
think would be accepted as a sufficient technique for 2.5.2, which
seems to stipulate that it must be possible to cancel a DOWN event
using only the pointer.

I wish I knew whether or not this behaviour applies to sliders.

Cheers, Isabel
