What steps will reproduce the problem?
1. Create a single block
2. Build a pattern based on it with an increment of 1
3. On the newly created one-element row, create a pattern based on it with
inc y = 1 and inc iterations = 1.
4. Move the nested pattern

What is the expected output?

The whole pattern should move around the screen.

What do you see instead?

The nested pattern (the one-element row) is left behind when the shape is
moved.

As with  Issue 198 , this bug is not consistent. It occurs more using Java
1.5 than with Java 1.6.
