Hi Kastor,
Thanks for the feedback. I will investigate and see if we can persist this setting in the next release.
By default, layout settings are stored in:
%AppData%\LogViewPlus\layout.xml
This settings file isn't really designed for sharing across multiple machines, but if you were to place it into a freshly installed LogViewPlus and the monitor configurations all matched, then it should work.
Hope that helps,
Toby
