DataTypes Library
The current version of the HTDS has some workarounds implemented to avoid some bugs/imcompatibilities with the DataTypes Library.

• To view internal nodes of an HyperGuide document, it was necessary to do a NewDTObject() call with SourceType set to DTST_RAM. But this failed in the datatypesclass OM_NEW method. So I had to implement a workaround for this and its only tested with datatypes.library V40.6. For datatypes.library V45 and above this workaround isn't needed any more.

• The datatypes.library provides a feature, which isn't documented : If you click in a datatypes object box and hold down the button while moving the mouse out of the datatypes object box, is does a autoscoll for that object. But the datatypes.library do not notify the application of the new position. The hypertext.datatype fixes this problem.
