Hi Marco, did you just install R2010a on your linux box? I'm assuming that this has never worked for you. Can you try the following: 1.) Enter errormsg = javachk('mwt', 'The doc command'); to make sure that you don't get an error. From what you described, I don't think you will. erromsg should be a 0x1 struct array. 2.) Enter helpUtils.isDocInstalled to see if this returns a 1 . 3.) Try the following command com.mathworks.mlservices.MLHelpServices.showReferencePage('fft',0) I suspect this will not work to produce the reference page in your help browser. If everything is configured correctly, this should produce the reference page in your help browser. I think you should use what you get back from executing the above and contact technical support, or have your local MATLAB administrator contact technical support if you are working in a networked installation. Make sure you have all your installation information including your java version available. I would use the commands that you have tried and the results (including the ones I have given you) to produce a script to explain what you have done and what behavior you observe. This will help them to quickly diagnose and repair your issue. Wayne
