Running roundup_0.7.1 on a Windows system.

The sorting on the List Issues page seems inconsistent.

The 'Group' function works ok - but need to use the 
descend tick box adjacent to 'sort on' to change the 
order of the groups.

The 'Sort' function works ok (ie issues are sorted inside 
their groups). However issues are always sorted in 
descending order.Neither tick box will affect this order.
