Known bugs:

• MolComp does NOT check the input for unknown symbols. It only checks it for the known ones. This normal requirement will be added to the next release. So, if you'll get an output like.M(NaCL)= 35.000550 (g/mol) (try it), don't panic, it found 1 Na and 1 C atom, L being ignored. Just input the correct formula, type NaCl correctly and you'll get 58.44...
• An usual organic chemistry formula as CH3CH2OH is not, yet, understood by molcomp. We are still workind on this feature.

If you just discovered an unreported bug, please tell us about.
