Actually, I did format both those "drawings" properly when I posted them, and they showed up fine both in the preview and right afterwards when I checked the thread.
The next day, on a different computer (same format) the first post appeared out of alignment, so I configured and posted the second one.
That night, the first post continued to appear screwed up but the second one looked fine (in preview and in the forum).

The next day the FIRST one looked fine again, but the SECOND one was out of alignment! Gotta be those *%!*@! elves!
