Update: RefTreeAnalyserRefTreeAnalyser has just been updated to version 3.1, build 211. Fixed issue with OK button of the ToC dialog not responding to a mouse click. Build 210 added: Now shows What's new, the first time an updated version is loaded. When timing formulas takes very long, RefTreeAnalyser will temporarily show an option to stop the timing. When you click the Precedents button (or its short-cut key) and an object is selected and not a range of cells, RefTreeAnalyser will show the references used by the object.
