openMorpho uses too much memory
0%
Description
Currently, Morpho needs 512M of RAM to run successfully. If it is set to a lower value, Morpho will freeze in the Data Table Wizard when importing a table with many columns.

I used my laptop to import the table - wtyburczy.29.1, which has lots of columns.
My laptop only has 512M physcial memory. During the test, I set 128M or 512M as JVM parameter to start morpho. In both case (128M or 512M), the morpho stopped working when it imported column 39.
Here is memory monitor result
