searching for a replacement of the usual m$word/chemdraw/endnote

i tried xdrawchem and chemtool.
didnt realy like these. combination with openoffice wasnt the way i
expected it, and i had other problems.
just found bkchem. i like python ... so it sounds all great.

you say that one needs python 2.2 which i have ... seems the setup.py
relies on os.walk() ... this is only in 2.3 ? or am i wrong?
other projects rely on python and i do not want to upgrade right now.
guess i can get the stuff to /site-packages manually.

Well, you are right. I have found that in the most recent versions some code that relies on things from python 2.3 has slipped into bkchem. On the other hand version 0.10.0 will require python 2.3 so I don't plan to fix this problem. If it would be possible for you to upgrade python, it would be the simplest solution. I am also playing with the idea of a binary linux build so I will try to prepare one for 0.9.0-final which should be out this week.

apart from that i have a problem with ... i guess ... the fonts? Pmw
works ok. demos and tests are fine.
but bkchem (started "locally" because of problem with setup.py) has
interesting little boxes after each letter. see screenshot.

I thing I can guess that you are running RedHat 9.0. Am I right? This is a known problem of this distro. I have read something on the internet about it. RedHat hacked the Tk/Tcl to work with 4-byte rather than 2-byte unicode strings and this is the result... (or at least it is the only explanation I have found). The solution could be to install python from sources, however one user already reported to me that it did not help him. Probably the best solution to this problem would also be the binary build. I will definitely try to prepare one.

any linux-user who could help me? thanks a lot in advance.
if Openoffice export realy works fine i will be very happy :-))
