To replicate:
1. In Squeak 4.3, open a new RectangleMorph.
2. Bring up the explorer on this morph using the halo.
3. Put the following into the code window and doIt:
self color: Color transparent. self borderWidth: 1
4. Save to a .morph using the halo.
5. In Squeak 6.0, open a fileList, navigate to the directory containing the .morph above, click on the entry for that file, click load as morph.
You will get an error titled:
Key not found: Color
I don't know if this list allows attachments or not -- I'll attach a .morph that shows this error and hope it goes through.
I've got other issues loading .morphs from my own subclasses of RectangleMorph where the borderColor is wrong, but I don't have a simple test case for a bug report yet.
-Thanks in advance, Jim
