If you can repro this in a small test app, file a radar right away.

I'm porting code from PPC over to Intel.
I have discovered the same interesting bug with several calls made
to the
toolbox call ::PtInIconSuite() in the Intel version that do not
exist in the
PPC version.
The bug is that ::PtInIconSuite() returns false when mouse clicks
are made
directly on the icon.
Variables viewed in the debugger reveal the mouse click is
contained within
the boundary of the icon rect.
Further runtime testing revealed mouse clicks 1 or 2 pixels outside
of the
icon boundary sometimes, sometimes, are accepted as true in
::PtInIconSuite().
It is almost as if the inverse of what is expected is being
returned by
::PtInIconSuite().
The toolbox call ::GetIconSuite() is used for reading.
Since this same code works fine on the PPC version, this leads me
to believe
there is a byte swapping issue with the icon mask (which the
documentation
reveals ::PtInIconSuite() tests against).
Since only the toolbox is used to read and process the icon, this byte
swapping (or whatever) issue is contained with in the related
toolbox calls
(::GetIconSuite(), ::PtInIconSuite(), etc).
Can anyone confirm this?
Has anyone experienced similar behavior in their code?
The "band aid" for this bug is to call ::MacPtInRect() passing the
mouse
point and the rect of the icon. Behavior is as expected, however,
the icon
does not highlight when clicked on. (The icon is highlighted when
clicked
on calling ::PtInIconSuite() in the PPC version.)
Thanx!
Joe
