Last change on this file was 11283, checked in by westram, 6 years ago
  • fixed some issues related to [11278]
    • added missing help
    • disable for non-experts
    • some logical fixes
      • do timer callback only (once) after need_recalc was set
      • checking 'auto calc' now instantly performs the calculation (if needed)
      • happens even automatically after ARB_DIST startup (if saved with properties)
      • if 'matrix autocalc' is checked, but neither 'tree autocalc' is checked nor matrix windows is shown (or would auto-popup) ⇒ only forget matrix
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
