 I am having some trouble with my first Intuition program and
I'm hoping someone can help.

I have a few image-gadgets that are giving me trouble. It seems
that when I run the program, some times the gadgets look fine and
other times they are just garbage. This happens between successive
runs of the same executable.

I know that Image data has to be in CHIP RAM, but I am currently 
doing nothing explicit to ensure this. From what I understand, if
the image is NOT stored in CHIP RAM, I am likely to get exactly
what I am getting. Now, my question.

1) I am using Manx 3.6a. Is there any way that I can have the system
	set these image structures up in CHIP RAM?  I know I could
	just do a MEMF_CHIP AllocMem() and copy the images into the
	new buffer, but that seems redundant. I suspect that 
	there is some neater way to have the initial declaration 
	guarantee CHIP RAM placement.


Any help on the matter is appreciated.

Jeff
