Summary: MOUSEMOVE's IAddress gone astray?

Followup-To:


I've been having a problem with prop gadgets and FOLLOWMOUSE.  It seems
that the MOUSEMOVE IDCMP messages I get have the IAddress set to the
window containing the gadget rather than the gadget itself.  The GADGETDOWN
and GADGETUP IDCMP messages have the IAddress set properly, however.
I don't have REPORTMOUSE set for the window, so I'm not getting MOUSEMOVEs
for the window itself.

This wouldn't be a problem except when trying to use multiple prop gadgets
with active tracking (i.e., update an on-screen value as a prop gadget is
"thumbed".)  Currently, I set a variable when I receive a GADGETDOWN on a
prop gadget, use the variable instead of the IAddress field for MOUSEMOVES,
and reset the variable on a GADGETUP for the prop gadget.  It works, but
not as elegant.

Am I doing something wrong, or is this an old bug?
