When you start PingPlotter Pro, in it's default configuration, it does not automatically start tracing to the targets you were using last time.  By default, PingPlotter Pro starts in "adhoc" mode, and it's ready to trace to whatever target you want to enter.

It may be, though, that you want to start tracing one or more targets automatically when PingPlotter Pro launches.  If this is the case, then it's possible to do this, you just need to set things up.  Follow these steps:

• Start tracing to the targets you want to use each time.
• Save a workspace to a suitable directory (Workspace -> Save Workspace As...)
• Go to Edit -> Options, and then go to the "General" section.  Turn on the "Auto-save/load active workspace" option.  This will cause your current workspace to save every time you close PingPlotter Pro, and it will automatically re-load each time you start it.
   
  
• You may also want to schedule auto-saving the active workspace, just in case your computer loses power or crashes.  By default,  PingPlotter Pro will only save the workspace when you explicitly tell it to, or when you close PingPlotter Pro.  Enter a free-form time (e.g., 1 minute, or 2.5 hours) in the time field.
• Now, close PingPlotter Pro.  Reopen it.  It should have all your previous settings / targets already tracing, and will resume where you left off.

Notes:

• If you start tracing to any new targets during a session, those targets will be resumed the next session as well, unless you close those targets.
• If you load any old collected data sets, and have that open in memory when you save a workspace, those targets will be saved in the workspace as well.  When you close and restart, targets that were in memory but stopped will still be stopped when you reload.
