After loading DAS/2 data, areas of the screen are greyed out. This is correct. However, there appears to be a disagreement between chromosome coordinate space and genome coordinate space. If, for example, refseq data is loaded for chromosome 1 of H_sapiens, then it appears in the correct location, but the area around x-coord 0 of the display is no longer greyed out.
Loaded data appears to drift slightly beyond the edge of the chromosomes, which is resolved as the user zooms in.
