I received a .shp polygon file. When I choose the edit toggle tool in QGIS the little red X's appear as expected. Then when I try to edit the polygons such as add a polygon all seems to go well, when finishing with a new polygon the dialog box for the attributes appears which allows entries and then upon closing the new polygon disappears. Also when trying to use the node tool it looks like a node can be moved but not really. Or any other editing such as editing the attribute by selecting a polygon with the information tool, the usual table appears and not the dialog table which allows entries into the attribute variables for the selected polygon. The file is not read only, other files are in the same directory which are editable. Any ideas what the difficulty is?

check the shapefile and containing folder (including .dbf, shx and .shp file) is NOT read only. – Mapperz Aug 7 '12 at 21:04
As noted, the files are not read only. Other files in the same folder are editable. Also I think in QGIS when editing a file, nothing is done to the original file until one saves the file. I figure this is true because the undo command works with all the operations in an editing session. – HealthMaps Aug 8 '12 at 23:55
Are topological editing and intersection avoiding enabled? Also you may try to save this layer as another file and try to see if it is editable. Try another GIS (SAGA for example) to edit this file to see if the problem is in QGIS. By the way you didn't mention your QGIS version. – SS_Rebelious Aug 9 '12 at 12:55
Did you check the attributetable if there is a new record created? Perhaps, your legend isn't set well, so the polygon is not shown in the mapwindow. – PieterB Aug 9 '12 at 13:13
I cannot share the file. How would I determine if it is a QGIS or data problem? It seems that re-exporting it as a different .shp file from another GIS which is now editable would indicate that it is a data problem. – HealthMaps Aug 11 '12 at 17:58
