=========================================================================
BugFixes (youngest to oldest):
(Note: dates in day/month/year)
20/5/09 v4.1 Added new checkbox to skip data lines where dip and direction were both zero
	Added routines to better preguess the data coulumns in new Tables and preserve the selection
	in subsequent calls to tables with the same headings
	Corrected some anomalies in the new expanded set of GeoMapSymbol Tables put on the web for download
15/5/09	v.4.0 Removed the requirement to enter dummy registration codes on initial startup. 
	Fixed several bugs in the Table selection process, particularly in the Where clause 
	that had been causing errors. Revamped the initial symbol drawing process and instituted 
	an automatic redrawing of any new symbols. Made some cosmetic changes.
30/11/03  Fixed bug in way new appending option was selected. 
6/9/03	Added current Selection to the list of Input Tables that can be processed. This allows 
	symbols to be plotted for only partial rows in a Table. Added option to append Input Table
	rows to Output Tables that have exactly the same structure as the Input Table. (Previously 
	the Output Table was always completely overwritten).
9/10/02 	Corrected bug that prevented tables without location columns being processed. Cleaned up 
	some of the error traps. Added GeoMapSymbol button to Tools toolbar.
20/8/01 	Corrected bug that plotted RH rule strikes in a LH rule orientation.
23/6/01 	Corrected bug in new version that prevented access to location dialogs 
	for tables with no pre-existing objects. Corrected minor annoyances 
	with final label Save dialog.
8/11/00 Version 3 released under new name
	New version automatically recognises and converts existing GeoSymbol.Tab 
	to GeoMapSymbol.Tab with no changes. 
	Added ability to use location of existing objects in Input Table to locate symbols 
	in the Output table. 
	Added option to preserve the full structure of the Input table in the Output Table. 
	Added automatic querying of how to handle symbol labels at end of plot processing.
	Added ability to preserve settings such as units, and symbol and label sizes, 
	between sessions. Values are stored in row 1 of the GeoMapSymbol table. 
	Corrected minor shape problem with the default Cleavage3 symbol shape 
	(replaced a missing tic mark). 	This correction will not apply to existing GeoSymbol 
	tables during the conversion to GeoMapSymbol.Tab. Either change it manually 
	(by replacing Node27 and Node29 of the row containing Cleavage3 with values 
	of -0.3 instead of 0.3) or delete the GeoMapSymbol. Tab tables and let GeoMapSymbol
	reconstruct the tables. This latter course will require registered users to re-install the
	registration of the product.

6/11/99 Fixed problem with handling input tables with deleted rows
2/11/99 Corrected major bug (arising from a minor interim recompile session in early October)
	that prevented dip columns being recognised correctly.
20/9/99	Version 2 released. Major changes to symbol definitions, capabilities, and interface. 
	Major bugs corrected include expanding to handle any coordinate system 
	(old version crashed if not Lat/Long).
