Sorting directories problems

[[HUN]Peti]

i've never checked it with older versions, but in 2.7 it isn't working...
if no one can find a solution:
1. set columns to "Full" (with ctrl+f2)
2. select the directories you want to sort with space (and NOT with insert)
3. click on the Size column header

i know what you think, this is slower, much slower
... yes, but currently i don't know about any faster way

is it possible that the problem is in Total Commander (I mean TOTALCMD.EXE)? could you copy over the TOTALCMD.EXE of 2.5 to the directory of 2.7? (you can install more than one TC UP instances on the same pc)
