Red X appears initially in new image windows

[curtis]

When a new image window pops up (e.g., from File > Open Samples > Blobs), there is initially a red X where the image should be, before it finally gets painted a second or two later. This is a cosmetic problem, but somewhat ugly, and may cause window packing bugs with certain L&Fs and/or on certain platforms.

I'm pretty sure this will not cause packing problems. I have debugged into JHotDraw and uts simply drawing a rect and two lines within the current preferred size.
