Hi Michael,

Are you trying to load a GTF custom track? I just tried to load the 
following sample GTF custom track, which contains quotes in the group 
field, and it loaded in the browser for me:

browser position chr22:10000000-10025000
browser hide all
track name=regulatory description="TeleGene(tm) Genes" visibility=2
chr22   TeleGene        exon    10000000        10001000        500     +       
.       gene_id "GeneA.mRNA"; transcript_id "GeneA.mRNA"; exon_number 1
chr22   TeleGene        exon    10010000        10010100        900     +       
.       gene_id "GeneA.mRNA"; transcript_id "GeneA.mRNA"; exon_number 2
chr22   TeleGene        exon    10020000        10025000        800     +       
.       gene_id "GeneA.mRNA"; transcript_id "GeneA.mRNA"; exon_number 3


For more information on GTF in the browser see:
http://genome.ucsc.edu/goldenPath/help/customTrack.html#GTF

 From that page, please note the following:
"The Genome Browser groups together GTF lines that have the same 
/transcript_id/ value. It only looks at features of type /exon/ and /CDS/."

If you are still having problems, please respond to the mail list 
([email protected]) with the type of errors you're receiving, and a 
short example of data that isn't working for you.
