The Help file says In case of problems, please check for a newer release at http://www.netsurf-browser.org/ and, if problems persist, email the support mailing list at netsurf-users(a)netsurf-browser.org. I am doing that, rather than using the bug-tracking system, because I tried the latter on a previous occasion and found it very hard to use. I attach a log file. NetSurf was working OK until a few days ago, when it took to crashing when started. I am not aware of making any change to my system, which is an Iyonix running RISC OS 5.11. (I am intending to install 5.16 soon but am deferring that until I have copied some applications and data files to a new computer.) At the time I thought the problem was with the particular website, but I have now found that NetSurf crashes even when started by double-clicking the application directory. I have reinstalled the latest version. I have also moved !Boot.Choices.WWW.NetSurf and allowed NetSurf to re-create that from scratch. None of that has made any difference. Richard
