Last Modified Date Often not Populated

Build 2360, Win 7 Pro, x64

Mathias,

there is an issue with Last Modified Date in build 2360 and the last 3 or 4 builds.

This happens frequently after re-starting MC.  F5 causes the column to be repopulated (of course), but I cannot pin down when or why it happens.  There is nothing in the logs...

Anything I can test?
