The screen snapshot _does_ help. It shows that the list of available dates for data in the Plot/Contour selection widget is blank ("----------"). This says that the widget found no data from the server request, or that something is wrong in the Tcl/Tk routine. Since I use this Tcl/Tk of the time, I have to imagine that there is no data available from your server. Let's troubleshoot! First, can you give me the name of the machine you are running your ADDE server on? If yes, and if I am not blocked from accessing the server by a firewall, then I can "point" to the server and list out what data it has. A couple of other things that have nothing to do with your problem: o first, I see that your McIDAS session is running with very small frames. I recommend increasing the size of the frames so that your view of the weather is nicer. The easiest way to do this is by starting McIDAS as follows: mcidas config This should pop up a GUI startup widget where you can select the size and number of frames you want your session to run with. I use a frame size of 650 BY 875 (lines by elements), but I occasionally use larger sizes. You need to have at least 17 frames, so make sure that you start with this many. o I see that your session came up with not only the MCGUI, but also with the McIDAS Text and Command window. In the GUI startup method I just recommended, you will need to select starting of McIDAS in one of three modes: MCGUI, Fkey, None. I recommend sticking with the MCGUI. After making your selection(s), make sure to Save the configurations to the defaults file. This will insure that the next time you start McIDAS using 'mcidas', a session with the settings you just configured will be presented. Now back to your problem. Once I have remote access to your ADDE server, I will be able to tell if you have data or not. You can test this out quickly, but pointing to a different ADDE server. You do this by: 1) clicking on the ADDE Client Routing Config button on the MCGUI (the button with two computers just to the left of the button with the big 'Z' on it. 2) clicking on the tab labled POINT 3) clicking the button to drop down a list of the cooperating community servers that you can get data from. Select papagayo.unl.edu and then click on the Update and Exit button at the bottom of the widget. 4) click on the Point Source Plot/Contour button on the MCGUI (just to the right of the button with the satellite on it) The widget should come up showing a date as a label for the button just to the right of label that reads 'Data plot day ->'. If it does, you should get a map of whatever value has been selected on the Map background. Tom
