browser crashes when:
1) 3 tracks are loaded: RepeatMarker track, RefSeq genes, and Mouse mm9 to hg19 blastz tracks,
and
2) region extended to chr22:21488,179-30,133,316 (I started from chr22:25,669,926-25,911,571 and did 5x zoom out twice, the crashes happened at the 2nd 5x zoom out).
Crashes happen on both chrome browser and firefox browser.
