I am using v4.0 Win Forms Map control with Visual Studio 2008. When I run a simple app containing the map control in debug mode, the map control only displays the word "Unlicensed" and does not show the map contents. In non-debug mode, it seem to work fine. I was able to replicate this with the samples project as well. We have a purchased and licensed version of MapSuite Desktop.
