Probably something simple but the UniTable class member list in the right-hand pane of the help screen has the first 2-3 characters on each line missing on my new WINDOWS 7 64-bit PC - no problems on XP.
We already fixed this problem with documentation. This fix will be included in the next UniDAC build. You can download the correct UniDAC documentation in the CHM or PDF format here: http://www.devart.com/unidac/download.html
