Unable to resize columns (size, downloaded etc) when double clicked

[midnightrosexs]

Started when I updated to Bittorrent 7.7.2. When I double click between say, Size and Downloaded, they don't resize. Not been able to find anything from a google search. Before hand, if I double clicked, they would resize how big the text is.

Edit - The only way I can do it, is if I press ctrl then +. Could it possible be windows setting than bittorrent
