Selecting columns is very slow
It takes an excruciatingly long time to select a column in a data table. On
Andrea's computer and on Veronique's computer, it takes up to 20 seconds for a
column to be selected after you click on the column header. On Dan's computer,
it takes about 4 seconds. All are PCs.
The search and open functions of morpho also take a long time to complete,
although not as long as the column selection takes.
