In the past when I had Tixati installed, whenever I clicked on a column name, it would sort the files in ascending or decending order.  Now after I had to reinstall my computer, clicking on the column name nothing happens.  Is this something that's wrong with the client, or something that I haven't set on the client?

To enable column sorting, go to: Layout > Sortable View.

Ah that's the ticket.  Thanks for the help.

thought that's the bug, tried to upgrade and finally started looking for the bug tracker, that is brought me to here ;)
thanks for tip, not-a-bug, everything is worked but just out of curiosity - why would make layouts not sort-able by default?
or if i choose is once, layouts would be sorted even after the next upgrade?
