Bill, As a possible supplement or alternative to CleanSlate, I use the following code near the top of a notebook: (* Limit a memory-consuming option. *) $HistoryLength = 0; (*-----*) (* The following interrupts on any message! *) messageHandler = If[Last[#], Interrupt[]] & ; Internal`AddHandler["Message", messageHandler]; (*-----*) If[True,(* Bring back in all the saved results from the fully \ evaluated file, that is, a prior evaluation of this file. *) (* The code that performs the \ save is at the bottom of this file. *) theSavedResultsFileName = StringReplace[NotebookFileName[], ".nb" -> ".mx"]; If[StringQ[FindFile[theSavedResultsFileName]], Get[theSavedResultsFileName]] ] Interrupt[];(* Pause after reloading symbols. *) Then somewhere below that, usually near the bottom of the notebook, I add: Interrupt[];(* Pause before saving symbols. *) (* The following saves ALL globals -- not necessary. *) saveName = StringReplace[NotebookFileName[], ".nb" -> ".mx"] DumpSave[saveName, "Global`"]; Saving all the globals is not always the best way to do this. Rather, replace "Global`" with a specific list of symbols whose value you want restored from the prior session. Good candidates are variables that take a long time to calculate.

In contrast, quitting the kernel would remove everything.
