Consider including in future help menus a summary of known problems and solutions encountered by DataCAD and users. eg. "cross suddenly locks into onto 3 angles when in B-tangents" : solution, "adjust TanDivs to 8 or more if it shows 3" etc. etc. This help 'database' can then be updated with each release providing a ready access to problems and possible solutions.
