Important: see Updated XTEXT Control Modules #2, which supercedes the following.
XTEXT now supports new versions of the underlying control modules TER18.DLL and HTS13.DLL, in addition to the earlier versions TER15.DLL and HTS10.DLL. Currently there are no new features being exposed, but the updates contain numerous internal refinements and bug fixes that might be applicable to someone.
Note that if you have TER18.DLL present, then you must also have HTS13.DLL. You cannot mix TER18 with HTS10.
Also note that if TER18.DLL is not present, A-Shell continues to use the previous TER15.DLL and HTS10.DLL. So if you encounter any problem with the updated DLLs, just rename or delete TER18.DLL to go back to the previously supported versions.
