I solved this problem by clearing my "cookies" and "cache".
In this case, "reloading" didn't work.

I am not sure whether this is a problem in test.Galaxy.
Today, I opened galaxy main and a UCSC window browser at the same time. You can see the screen shot for the two browser tabs sitting together. And in UCSC Browser I searched for a Known Gene -- Zfpm1.
Then, I went back to Galaxy to "get data" from UCSC Main table browser, if u r careful enough you can see the "click" (dotted-line square). But the middle frame came out not to be the table browser but the page I opened in the independent browser.
So seems Galaxy doesn't work well if you open an independent UCSC browser at the same time.
