Looking at the on line help for DirectoryStack it shows the following example: SetDirectory[$InstallationDirectory] "C:\Program Files\Wolfram Research\Mathematica\6.0" DirectoryStack[] {"C:\Program Files\Wolfram Research\Mathematica\6.0", "C:\Program Files\Wolfram Research\Mathematica\6.0\Documentation\ English\System\ReferencePages\Symbols", "C:\Documents and Settings\roger\My Documents"} However when I request a DirectoryStack it never shows the top item SetDirectory[NotebookDirectory[]] /Volumes/RamDisk/D1 line <--this is correct DirectoryStack[] "/Users/phillman5" <- missing new stack value set above However if I do a Directory[] I do get the top entry Directory[] /Volumes/RamDisk/D1 line On starting Mathematica it shows that the DirectoryStack is empty. Also ResetDirectory[] shows the resulting top DirectoryStack item, not the one popped. I am using Mathematica 7.0.1.0 on Mac OSX 10.6.8
