Revision:	1785
Committed:	Wed Aug 22 18:43:27 2012 UTC (12 years, 8 months ago) by jmichalk
File size:	10539 byte(s)
Log Message:	Trunk: The changes in this commit are confined to applications/staticProps and for the most part deal with a misspelling of initialize. The one other change took place in StaticProps.cpp and deals with the default treatment of sele2. It had previously been set to 'select all' which seems to go against what would be desired by not specifying it with regard to proper operations of many of the analysis programs ( g of r's especially)
