Re: menubar color problem - OSX

We are seeing the exact same behavior using Prograph CPX. All Quartz rendered text on a G4 in millions of colors mode is unreadable. Nobody has been able to point out where this new requirement is documented.

The *only* sort-of solution we have come up with so far is checking the color depth at app startup and forcing it to "Thousands" so we can show an alert explaining what has happened. How lovely is that?

We may be able to skirt around the problem by generating code libraries of API wrapper calls but the jury is still out on that idea. It is certainly a huge amount of work.

Otherwise the only thing left is requesting users open the app in classic, where everything looks fine, if they need millions of colors on the G4.

One things is for sure: Apple believes this "Behaves Correctly" and appears to have no interest in helping those of us afflicted with this find a solution, other than suggesting we start from scratch using C.

If I'm going to use C, I'm probably going to do that in Windows, but then again, Prograph runs just fine in Windows.

Oh well,
Jack

P.S. How about a list for those who have lost their livelihoods to AltiVec?

Might be a stack-alignment problem with Altivec instructions (you'd see it on G4 machines only). CoreGraphics has dealt with similar problems (always with applications *not* written in C/C++), not so long ago.

A report from a beta tester of our application reports the
following strange behavior of the color of the menubar.

I played with it a little more, and have a little more detail to give
you. This is in Mac OS X 10.1.2 on a dual 800 MHz Powermac.


I've seen a light green, yellow and purple so far. I wasn't able to
get green this past time I played around with it though.

This only seems to happen when invoke the open command, am in the
file chooser (that is NavChooseFile selected from a menu item)
and double-click the name instead of letting it give me
the preview (the previews get old very fast). The first time, the
menubar turns purple. The every time after it turns yellow. Except when
I change the folder in which I choose a file; in that case, it turns
purple again. Then as long as I'm opening files in that folder, the
menubar turns yellow every time after the first time.

If I hold the mouse down and pass it over the menubar, the menus turn
black, as normal.

Has anyone ever seen anything like this? Does anyone know
what the problem could possibly be?
I can't send a simple example because the application is not
written in C and there is a lot going on, though it does seem
the problem has something to do with NavChooseFile rather
than actually opening the file chosen.

I do not have a dual processor machine to test on and the problem
does not happen on my single processor machine. Most, if not all,
of our other beta testers are using single processor machines either
because that is all they have or because there are some as yet
unsolved problems with floating point computation with our
application on dual processor machines.

Thanks for any insights.
