Hi, sorry to bother with another question after only a few hours... but I still have some doubts on the startup of Maya 5.0. Whenever I start the program, just before the initialization process is completed, the following error message is displayed in the Command Feedback line, for less than a sec: Error: Could not create command port : old-odxe7caj97o:7845 If then I open the Script Editor to display more of the history, I can check that this error message is located among the very first command lines, as follows: file -f -new; // Result: ./untitled // docServer(1); // Error: Could not create command port : old-odxe7caj97o:7845 // // MayaLive version updateRendererUI; ... ... Could someone please explain the reason for this error? Still I do not understand why the Output Window shows up everytime I start Maya 5.0. Thanks again for your help, Avoosl
