We sometimes receive critical error messages in ESS where the first couple of lines give a summary of the issue and then the rest (sometimes a couple of pages)is details about where exactly the error took place like com.sap.pcuigp.xssfpm.java.MessageManager etc etc. I am wondering if there is any way that these details are not shown to ordinary users, but just the summary of the error. There is a tray at the top which is expanded, if this could be collapsed it would do the trick. Are you aware of any such setting?
