ERROR
When adding a Theme to a View, opening a Project, or turning on a Theme ArcView returns the error; Stop: Assertion "Number of bits in range" failed at line 351 of file "../base/bitmap.c"
The shapefile is corrupt.
Restore the shapefile with a back up copy. If no backup copy is available you may have luck repairing the shapefile with the Shapechecker utility. Andrews ArcView Page has a utility to do this (see link under Related Information). Click 'How to / Useful' on the left and then ShapeChecker. Follow Andrew's instructions to download and use the utility.
