Update History

This document describes the changes that have been made to the InstantTrack Frequently-Asked Questions page since its initial publication.

Version 3.0 - March 1, 2019
InstantTrack is now free to download or distribute.
Version 2.22 - September 22, 2007
Added a section on 64-bit Windows. InstantTrack won't run natively in these environments, but according to a report from VK6KCH it can be run successfully under DOSBox.
Version 2.21 - September 6, 2007
Added a section on Windows Vista. InstantTrack runs on Vista but special workarounds are required in order to use the map screens.
Version 2.20 - April 29, 2006
Added a section on the message Problem with map: can't open file and split that off from the section on insufficient memory to load the map. Moved both map answers up next to the section on map screen text garbage, and renamed that chapter "Map Problems". Removed obsolete references to the old AMSAT web site. Updated link for XT-CE. Updated AO-40 entry to reflect its demise. Removed N6NKF's email address, which is no longer valid.

Added an item about true North versus magnetic North.
Version 2.16 - February 29, 2004
Added an item about Keplerian elements (not needed) for the Sun and moon.
Version 2.15 - February 24, 2004
Clarified that the version number at the top of the document is the version number of the document, not of InstantTrack itself.
Version 2.14 - January 24, 2004
Changed "new version expected in early 2001" to a reference to the latest beta test download, for the timezone_offset_seconds feature. Added a reference to the tutorial on Downloading Keplerian Elements for InstantTrack. Added a reference to the SAREX mailing list for ISS Keplerian elements. Corrected "Daylight Savings Time" to "Daylight Saving Time" throughout. Corrected numerous small HTML syntax errors. Added a caution about timekeeping in dosbox on the Macintosh.

Version 2.13 - January 8, 2004
Added information about running under the DOS emulator dosbox, updated the information about Virtual PC to reflect its purchase from Connectix by Microsoft, and removed the information about RealPC, which turned out to be permanent vaporware.
Version 2.12 - September 4, 2003
Updated references for Keplerian elements for Mir (no longer in orbit), the International Space Station (weekly bulletins might not be frequent enough), and AO-40 (separate elements updates no longer updated, use the weekly bulletins).
Version 2.11 - July 9, 2003
Documented the strange trick that Windows XP plays with real time when InstantTrack is minimized.
Version 2.10 - April 4, 2003

Version 2.07 - January 7, 2002
Corrected the answer about upcoming versions to reflect the fact that support for oddball timezones was fixed in version 1.51. Also reworded the answer about running on a Macintosh to reflect the fact that SoftPC is no longer a current product. Also noted that ITPASS is now available for free download.
Version 2.06 - January 5, 2002
Added Windows XP to the list of supported Windows versions.
Version 2.05 - August 19, 2001

Version 2.04 - August 18, 2001
Updated open beta listing to remove the exact number. Open betas may change faster than this FAQ! Also added some text to the section on AO-40 attitude entry to describe what version 1.51 and later do about that.
