I accidentally used a bit of syntax in TUI 1.6 that requires Python 2.5. I will release a new version that supports Python 2.4 when I have a chance. Meanwhile, if you have Python 2.5 or are willing to upgrade then you can use TUI 1.6. If not, please wait to upgrade. Note that I do not intend to support Python 2.4 for much longer. Python 2.5 has been out for a long time and Python 2.6 is current*. Upgrading your Python is a good idea in any case because Python 2.5 and 2.6 are significantly faster than 2.4. -- Russell *Python 3.1 is also current, but is a different language branch. I have no plans to switch until 3.x becomes mainstream. APO APO APO APO APO Apache Point Observatory 3.5m APO APO APO APO APO This is message 1137 in the apo35-general archive.
