Grrrrrrr... I am really starting to hate the Publisher extension of ArcGIS 9.0. God knows how many times I've tried to "compress and lock" my shapefiles but the goddamn extension won't let me do it.
Gotta upgrade to 9.2 very, very soon before I lose it. But then I'm going to have figure out what a "file geodatabase" is.... ugh. Thanks ESRI, thanks for nothing.
