im using ubuntu 13.10 64 bit and tixati 1.96, i cant set download directory to other partition (windows,ntfs). i can successfully do this operation in other torrent clients successfully.

I can't set mine, either, but I'm using Windows 7 Professional 64-bit, SP1. The Select Download folder window hangs. When I click on something, I get a processing circle until I get the Not Responding message on the window's title bar.

Edited to add: Uninstall 1.96 (64-bit) and installed 1.94 (64-bit). I had a new install of Windows 7 that I put 1.96 on, but 1.94 had worked just fine previously with the same OS on my old install. Now 1.94 doesn't work, either, with the same problem.

I'm going to try installing the 32-bit version to see if it changes anything.

Edit 2: Changing to 32-bit corrected the problem with Tixati freezing when trying to set a download directory for me (Win7 64-bit SP1).

I am having the same problem in Windows 7 64bit. When I click on computer to pick a different share the program freezes.
