6 of 6 C/Front Limitations Microsoft ® Windows ® does not go in to standby or hibernation if there is an open server connection from C/FRONT. Entries made by C/FRONT does not fire triggers to execute any code validation. Licenses must be correctly loaded on client and server. Every connection in C/FRONT is treated as a session. As with regular Microsoft Navision, the client and ODBC, the versions of CFRONT must match the version of the SERVER that you are trying to connect to. Only active keys are available to C/FRONT.
