Still WFM, please provide the lines from your `help->debug messages` that I posted, and what desktop you are using.
Note that the line not being wrapped is correct, changing the preference does not wrap/unwrap already open files, and a file that is open has its state saved when Geany is closed and re-opens in the same state, in this case unwrapped. This is because wrapping is a per-file setting `Document->Line Wrapping` so a user can set it to be different from the preference, and that is respected. The preference will only apply to newly opened files.
