Hi folks, I just wanted to leave you all with an update as to the issue raised earlier this week by Joon and Paul regarding the use of perl/Tk 804.025. This message concerns linux and unix users and OSX users who know how to build everything from source. This is not an issue for Windows users because I have built the executables for the programs using an version of perl/Tk taht is not effected by the problems I will discuss below. The version of perl/Tk currently being distributed at www.cpan.org is version number 804.025_beta5. If you go to the CPAN website or use the CPAN interface to install perl/Tk from the command line, you will end up downloading that version of perl/Tk. In response to mail from Joon and Paul, I downloaded and installed that version of perl/Tk and have come to the conclusion that it is too unstable to be reliably used with Athena and Artemis. One of the problems raised by Joon and Paul was, in fact, my own bug. However, there are several other serious problems that are bugs in perl/Tk 804.025 and so are out of my control. For the foreseeable future, I urge everyone to use an older version of perl/Tk -- 800.024. I keep a copy at my web site: http://leonardo.phys.washington.edu/~ravel/misc/Tk-800.024.tar.gz Athena and Artemis are very well tested against this version and do not require any of the functionality offered by the more recent version of perl/Tk. I will keep my eye on the development of perl/Tk and let people know when I think it is acceptible to upgrade to the more recent version (which will have some nice features, such as unicode support allowing e.g. Japanese speakers to keep their project journals in Japanese). I hope this hasn't been too confusing for anyone and I want to again thank Joon and Paul for their input as I worked through this issue.
