OK. >A quick check shows that the surface data displays correctly. However, >I have new problems with the upper air display. From the main menu, >SF7, F2, F3, F2 brings up the Upper Air Contour Plots gui. > >* If I click on Plot, accepting all defaults, correct data is displayed. >* If I change the day, the hour shown in the Time entry box changes > from Latest to the hour of the latest _surface_ data. This is bad! >* That's not good, but if I move the mouse over the time entry box > and menu, an Invalid Selection window opens and flashes rapidly -- > locking up the gui. That's real bad. This is caused by the previous bullet being bad. >* BTW, if I change the hour first, then the day, this does not happen, > and the correct data are displayed. OK. I looked into this problem (man, is the Fkey menu Tcl/Tk stuff ugly!) and came up with a fix. I stuck a new bkgmap.gui out in the pub/mcidas/src directory of anonymous FTP on our FTP server for you to grab. >>From address@hidden Thu Nov 7 13:26:31 2002 > >Another problem with the Fkey menu, at least on 7.8, occurs when >displaying a vertical cross section from upper air data. > >From the main menu: SF10, F1, brings up the Rawinsonde Cross Sectons: >gui. > >The default corridor half-width, 150 km, is too small.

Entering the command >produces the cross section. UACROSS is a lot more sensitive to the corridor width than XSECT/XSECG was. Since UACROSS is the routine that is used for ADDE data, I change the default from 150 to 300. I also changed the range of the width to 10 to 1000. I put a new copy of xsection.gui in the pub/mcidas/src directory of anonymous FTP (the same place as contains the new copy of bkgmap.gui) for you to grab. >After the initial error, if one returns to the gui and tries to use the >slide bar to increase the corridor half width, the slide bar does not >move and a new window opens, titled error in tcl script. I did not experience this error, and, quite frankly, I am stumped for how the program being run could affect the GUI selector. I will keep an eye out for this problem, howevef. >Another fkey problem next time, Bill Might as well send as many as you have so I can focus on the Fkey stuff. Thanks for the bug reports! Tom
