<p>There was a bug when saving that session, so that session file is unusable. We have changed ChimeraX, so if there is a problem saving the session, it will let you report that as a bug instead of leaving you with an invalid session file. The fix is in ChimeraX
0.9. However, at this stage of ChimeraX's development, we recommend that you often. At least as often as when there are production releases :-). Monthly, wouldn't hurt.<br>
