Things are getting weirder. Usually I have just installed one version of Therion over top of whatever version I have installed, but wonder if this might be contributing to issues I have here. After I have installed 5.4.1 over top of 5.4.0. If I open a thconfig file, with Help About I get 5.4.1 reported, as below If I then open a .th2 drawing file, I get 5.4.0 reported, as below So with two instances of XTherion open at the same time, each is reporting a different version. Same thing happens installing 5.4.1 88c8a06 over top of 5.4.1. The drawing editor still reports 5.4.0 Perhaps a harmless bug/omission or something odd with the installer? Initial drawing suggests the drawing editor is behaving like 5.4.1 (triangular survey stations).

A while back I reported problems with beta versions of Therion related to 'loop-closure survex'. They were fixed in 5.4.0 Now using 5.4.1 those projects/thconfigs that crashed before now seem to be OK, but I have now found another project/thconfig that crashes with 5.4.1 but not with 5.4.0 5.4.1 runs OK with 'loop-closure therion' but gets killed by Windows 10 when I use 'loop-closure survex'. Am still using survex 1.2.27. I have attached the log file with 'loop-closure survex'. Not sure if it is related, but I notice that if I install 5.4.1 'Install Only for Me' it will not overwrite a previously installed 5.4.0, even though the installer does not report any errors or problems to the user. Ie it fails even though it looks like it has worked just fine. To get 5.4.1 to overwrite 5.4.0 I need to "Install for all users". Bruce
