Jay, thanks a bunch for posting that market depth file for me. Mr Bud is right, though -- it has entirely to do with the T&S side and not the bid/ask fields... The same thing happens as I described before. This is the file you sent me that I've modified to display T&S data also...you can see that the black void is still a problem when I try to make the right side smaller...
bungrider, just grab the area that separates the level 2 quotes from the Time & Sales and move that over to the right to narrow down the Time & Sales portion.
