GeoBase 4.18 Release

Telogis GeoBase 4.18 is now available (login required). This release corrected an issue that could cause the GeoStream server to run out of memory when the background task queue exceeded its capacity and an issue in the MapCtrl class's DragBehavior property, which caused a box to render incorrectly on high-DPI displays.
