GenoViz

I discovered this when trying to show students how to get IGB to show
labels for gene models in the main display.

What happens is that unless the user clicks another row in the Preferences
Menu Tiers tab, the request change does not take place.

To fix, I would recommend adding a new button called "Apply Change" to the
Preferences Tiers tab, so that there will be no doubt about what a user
wants to do.

To repeat:

(1) Launch IGB.
(2) Choose Species A thalian and Genome Version A_thaliana_TAIR9
(3) Load Bioviz (Quickload) data set TAIR9 mRNA and zoom in close to a gene
model, so that a label could be drawn if the application were configured to
do so.
(4) After loading, click File->Preferences->Tiers

(5) Now, click the cell under heading "Label Field" and type "name". Close
the Preferences Window.

Note that IGB does not display any labels on the annotations.

(6) Re-open the Preferences window for Tiers and this time click on a
different cell in the window. Close the window.

Now, the names of the gene models appear as labels in the main display.
