?Dear All, Sorry... another bug report! Hopefully the last one for a while! In the history window some, but not all, data from previous fits seems to get overwritten when running a new fit. Specifically I've noticed this happening with the information in the "Data set" section. To reproduce run a QFS fit with some R-space fitting windows (say 2-4); at this point the log will be displayed correctly in the history window. Now change the R window (say 1.5-3.5) and run the fit again. When you go to the history window the R window information will be displayed correctly for the most recent fit but, for the previous fit it will have been overwritten by the newer fit. Some of the other info, such as R-factor by k-weight seems to get overwritten too. A video of this behaviour can be found here: https://wwwa-e.ucl.ac.uk/cgi-bin/dropbox/dropbox.cgi?state=pickup_info&id=29d3e5c2 password: 54c8545f System info: Win 8.1 Enterprise x64 running Demeter 0.9.22 pre release x64; log attached.
