Crazy imageData

[Troy Rollins]

My stacks do some moving of imageData between main stacks.

The code seems to break, randomly, but with regularity. I think I have 
the issue resolved, it works fine for a while, then suddenly doesn't 
work... with no changes to any of the related code. It looks like this 
-

PUT the imageData of image ID 1018 of stack "Button Icons" into 
tClearImage
     set the imageData of image "ThumbNail" of card tClipSelected of 
stack "CurrentP" to tClearImage

*Sometimes* this will work a hundred times in a row. Then, it will 
suddenly fail, and fail every time after that.

A little more info -
image ID 1018 of stack "Button Icons" is an imported JPG, but I've 
tried PNG, and GIF with the same results.
When it fails, the image is pure black.
"Button Icons" is a substack of my main app.
"CurrentP" is a  mainstack, loaded by my main app as a resource.

It seems to me that although I have the paths right, it can't find the 
proper image?? The fact that it works *sometimes* but not always is 
just weird, as computers usually make the same mistakes consistently. 
Could this have something to do with the defaultStack? I didn't think 
so, as I'm not using "this stack" anywhere, and I explicitly define the 
stack names.

Any pointers? Thanks.
