[imp] Problem with Sorting

[Manuel Schwab]

Hi list,

I have a problem.

If i login to horde and use IMP, I can't sort the messages.

The messages are sorted by the ID column.
If I click on the column head "Date" or "From" nothing happens.

Is this a configuration problem or is there only the possibility to sort 
via "ID"?

Thanks for your help.

Manuel
