Avogadro Bugs

This repository is mainly for the discussion of crashing bugs or otherwise serious avogadro issues. You may use this page to add or edit bugs, perhaps even reporting them to the sourceforge page.

The most important bug to know about is #679 causing crashes when replacing groups with hydrogen. The upshot for students and demonstrators is that you should always use Build > Add Hydrogens instead of trying to draw them manually.
Avogadro doesn't appear to be able to export jpegs, however it exports pngs just fine
If exporting from ChemDoodle/ChemDraw use .cdxml not .cdx as the format as the latter will not import correctly (bug #644)
When rendering both the results of a QTAIM calculation and the MOs of a .fchk file, Avogadro often crashes (only attempted on OS X but the QTAIM plugin is only compiled for OS X as of 16/07/13) #683
It is possible (and arguably very easy) to close the orbitals dialogue after loading a .fchk file. This leaves the user rather stuck as there is no way to regain it without reloading the file. Individual MOs may be loaded however by going Extensions > Create Surfaces... > Molecular Orbitals (also has the advantage of counting orbitals from the bottom up not the HOMO down).
If you have just completed a QTAIM calculation and the molecule is not rotating, then you are probably in draw mode and have just deposited several invisible ethane molecules with your mouse clicks; Select Ball-and-stick in the display types, Press F10 and then Ctrl+Z as many times as necessary.
