[Genome] VISTA link to UCSC-display issue

[Joanna DiSpirito]

Hi, I am having an issue with genome browser display.

Browser: Firefox 2.0.0.14
Macintosh, OSX 10.4.11

I am not sure why my problem happens, and if it is a general problem with many
genes, or specific to my region of interest, so I thought I would explain what I
did and see if someone else tries this, if it also happens to them.
I have linked into the UCSC Genome Browser via a VISTA pre-computed alignment of
the human and mouse genomes.

-From the VISTA "browser" homepage, I  entered "Ifng" in the position column and
checked the bubble for "VISTA tracks on UCSC Browser" as the alignment
visualization method (using the human 2006 sequence as the reference seq)
-The aligmnent opened in UCSC. It was in a window that was 620 pixels in size. 
-I increased the pixel # to 1200 because I wanted a larger window.
-The window enlarged, however, the region displayed jumped from Ifng (chr 12:
66,834,817-66,839,788) to chrX:151,073,054-151,383,976.

-If I then entered the above coordinates for Ifng into the UCSC
"position/search" box, the region displayed jumped back to Ifng(chr 12:
66,834,817-66,839,788). However, the window went back to 620 pixels.

I don't know if there is some setting that I have turned on that is not allowing
me to view the region that I want as an aligment, at a pixel size of 1200, or if
there is something about the data as it is shown that is incompatible with a
window of that size, independent of browser settings.

Any help would be appreciated.
