Selecting reference genome is weird

[AlistairNWard]

Once the file URL is added, you need to select the reference genome (I'm doing this from a GNomEx link).

1. Select GRCh37.
2. Wait a while, and then the text in the reference drop down returns to "Select reference genome..."
3. Wait a while longer and you can click "Go". Sometimes clicking fails.

This is intermittent and sometimes does other things.
