Tixati, pls release a v2.16-2 with bug fix early as i tried to go back to v2.15 & this bug has taken over the old version too :(
I reported this bug some time ago.

Then I thought to go back from 2.16 to 2.15 and did that. Then I read your post and tested if 2.15 was, now, also affected with this bug. I can confirm that this bug now also occurs in 2.15 (if you have previously used 2.16). So I wonder how that can be? Suggests to me that the source of the bug must be in the data files that Tixati uses. Mmmm...
I completely agree that Tixati should release a 2.16-2 bug fix as soon as possible.
In the meantime, for people who rely on auto-shutdown when the queue is finished, then a good workaround program to use on Windows systems is "AMP WinOFF".
