I investigated and found that there was some strange interaction going on between the setScale procedure included in xsection.gui and the one contained in upcguiprocs.tcl. To get around this, I simply renamed the procedure in xsection.gui to mySetScale. I also pared it down to do just what was needed for the cross section plots. >Then I loaded a radar display. The load center still is reset. ??? OK. Looks like I commented out only the first of two sections that needed to be removed. Thinking about why this was ever done I remember that way back the McIDAS station database did not have the locations for all of the NEXRAD sites. Give this, I had to read a table to lookup the locations and use those values when doing loads. The logic error in the way I did this was to not account for the situation where a user specified a load station location ID that was different from the NEXRAD ID or when the user specified a Lat,Lon location. Both of these situations have always been OK, so they should not have been altered. Since the McIDAS station database in 7.8 _should_ contain all of the NEXRAD locations, the special logic to lookup the NEXRAD location is not needed. Given this, I commented out both sections of code in imagloop.gui. So, if you regrab xsection.gui, imagloop.gui, and for good measure bkgmap.gui, you should be able to plot things with no problems. >A very appreciative, Bill Talk to you later... Tom
