EdUser32.exe should not be used to Edit a full MonTel sites PABX.INI file. By design, EdUser32 saves only a subset of the full details of EdIni32 - being only the details required by the Freeware Applications Ext32 and TzUtil.
EdUser was mistakenly distributed with some version of MonTel. To prevent it being used it should be deleted from the MonTel Application Directory.
Please note that there are NO PROBLEMS using EdUser32 in NON MonTel sites, that is when being used exclusively with the Freeware Applications.
Note: All Eduser32 features are included in EdIni32.
