I am having two problems using Color QuickDraw and would appreciate any
advice or insights.

1.  I am converting PICTs to my application's objects: I am using the
QuickDraw standard procs to do this. For bitmaps, I just want to
create another picture so I am opening a picture and calling CopyBits
with the arguments that are passed to StdBits. I copy to the BitMap of
the current grafport. This works fine for black and white bitmaps but
I crash with color. Can anyone help. I have seen other references to
this problem but no solutions. I've tried it with some pretty small
images and still crash.

2.  I have a palette of different colors to choose from. Since there
is only one palette in the application I use the Ghost Window global
to get it to float.  This has worked fine with a small amount of extra
code except the palette manager does not change its colors when the
ColorPicker is called and a palette entry is changed. I suspect it has
something to do with the fact that it is a ghost window and am
wondering if this is an impossible combination or if there is some way
to get this to work. If I change the color entries myself by calling
PaletteToCTab(), the colors will change but only after calling the
ColorPicker a second time.

By the way I've heard that System 7.0 has floating palettes; is this true?

Thanks in advance.
