When I mark some files as Read Only from Geany, exit Geany(save files in geany session) and then start again Geany. Files, which have been marked as Read Only are now not marked as Read Only.
If someone figure out this bug, please try to add information in which window of Geany the file was opened (if it is possible to open the same amount of geany windows as when geany was closing). This could be very nice feature, because i sometimes need to work on two projects and the next day continue in the work.
I think that little improvement of geany.conf and section files will figure out this.
