Using the "Collisions" link within the text turns on the visualization of all collisions (molecule-molecule as well as molecule-wall) rather than only the visualization of molecule-molecule collisions. However, the subsequent "Collision Density (Molecule-Molecule)" measurement in fact only counts molecule-molecule collisions. Remedy: Use "Model Customize..." to adjust the setting for collision visualization.

However, in the Windows version of SPARTAN Student Edition (the other versions are not affected) an "Unsupported" message may be displayed if a calculation is set up with the Calculations dialog. Remedy: Open the .odydata file. The first line contains "keywords"—add the following keyword at the end of the line: MMFF.

When building systems (SPARTAN ODYSSEY), the first component must be entirely built prior to the second component, the second component entirely built prior to the third component, etc.

The mouse-over "tool tip" for the Reload button says "Reload First Page of this Topic" even though the reload takes the user back to the current (not necessarily first) page.

Saving of models with ribbon representations in the .odydata format leads to program crash. (The .xodydata format works fine.)

When a snap plot is generated and the independent variable is changed by editing the corresponding number field (as opposed to using the adjacent slider), the Record button may become inoperative: no new datapoint is generated after clicking on the button even though it is "lighted up". Remedy: Click on the model background once, then reselect the Record button.

Incorrect values will be recorded if many properties (more than ~10) have been added to the list.

Snapshots of models will not print correctly if the Properties table is shown and a property is "active", i.e., selected (indicated by a blue background behind the property name). No problems occur if all properties are inactive ( = none is selected).
