Ralph has been updated to 5.29. In this version, we mainly address two problems seen in 5.28 update.
1. fix a problem of job errors when application is supended, removed fromm memory and restarted again.
2. fix (hopefully) the widely observed \"File Handle Exception\" eorros when full_atom graphic is turned on and off.
Users are expected to see in the \"Searching\" box that when \"Searching_Backbone\" is on, only backbone is drawn and when \"Searching_all_atom\" is on, backbone plus sidechains are drawn. Sidechain flickering is turnned off in this update as it might also be responsible for the \"File Handle Exception\" error.
Please report bugs in this post.
