We're having a problem with ApplySort for an mmBindingList. Specifically, in some cases the following code crashes -- I've inserted what I think is the crash log below.

if (dt.Count > 0)
dt.ApplySort(e.SortPropertyName, dtDirect);

One example is e.SortPropertyName is "EFFECTIVE_BEGIN_DT", and it's a column of 4 datetime values. None of them seem to be null or anything special.

In some cases, the system just seems to lock up, rather than causing a proper exception. The problem can also happen on numeric column, but I haven't seen it happen on a text column yet.

It almost seems like ApplySort only works on string fields, although it doesn't seem to give a proper error message to that effect.
