Morpho

On WinXP, open morpho and click on the "Open an existing datapackage" link on
the first page. The "open" dialog pops up, and sometimes, the ordering of the
entries in the list is incorrect (initially listed by "last modified" date).
However - clicking on or resizing the "open" dialog (and thus triggering a
repaint) causes the list to be painted in the correct order.

It seems that the list has, in fact, been ordered proerly, BUT the UI hasn't
been refreshed to show the new ordering.

NOTE that this problem is not repeatable 100% of the time - it happens only
occasionally (say 30% of the time). I have had this problem both on my work
machine and my home machine, both running XP. Not tested on other platforms
