I've uploaded the latest version of Element Manager to: http://www.eoss.org/elementmanager/download.htm Bearing in mind the comments on Line0, I have added the visual data and radar cross section as I originally proposed. IE: vis data per Molczan/McCants format and the radar cross section starting in column 40 and running 9 columns long to column 48. I believe this keeps me out of others territory. HOWEVER, the program does use an external file to hold this data and you need not save the file with that data if you wish to keep this area of a Line0 blank. Of course, you will not be able to preserve any underlying data should you wish to sort on radar cross section or visible magnitude. For details on how this works see: http://www.eoss/org/elementmanager/mainscreen.htm or http://www.eoss.org/elementmanager/version.htm Another new selection criteria, the International Launch Designator. You can select out by year, launch numbers and pieces. So, you could look for all the primary (launch piece "A") launches in 1966 if you wished. And you can select out all elements of a particular launch by selecting a particular year and launch number. Whatever... With the ability to search on more terms it was necessary to redesign the layout of the selection screen: http://www.eoss/org/elementmanager/selection.htm Also some counter intuitive stuff on the selection screen has been cleaned up. The Activate All toggle button has been replaced with a deactivate all button. That's all it does. With so many selections possible, I thought it best to have a guaranteed way to turn off all selections. The "Clear All Selections" button now behaves in a somewhat more expected manner. Click it and everything selection is made inactive and ALL values return to their defaults. The difference between this button and deactivate ALL, ??, the Deactivate all leaves all values intact just turns them off. There was a bug that caused the program to crash when run in a different regional setting than English when opening the Tracking Screen. That's fixed. Other stuff check out the version.htm page above for a full roundup. Other minor cosmetic changes to move toward added intuitiveness. That's it! 73 -- Rick PS. I can strip out all the detail in the radar cross section as Phil Rogers suggests. Suggestions welcome. I just thought that since this feature was added specifically for a radar observer, he might want that level of detail retained so he could have access to the full reference data.
