## Miscellaneous

- changes in option values in some cases do not take effect immediately but only after GPSMan is restarted. Some care should be taken to avoid inconsistencies due to this. In particular, changes in the distance unit affect the possible values for the initial map scale, so that a change in the latter is normally needed in the next session after changing the former.

- in order to prevent inconsistencies, windows presenting results that depend on the definition of an item, such as computations or graphs, may be (but is not guaranteed to be) closed by GPSMan when the item changes after being edited or being replaced when data is read-in.

- anything that looks like a button normally is a button.

- closing a window from the window manager may cause data to be lost, and GPSMan may be unable to create it again.

- at any time only one waypoint, one route, one track, one polyline and one group may be open for editing; other such items may be viewed but not edited.

- when exiting from the program (`GPS Manager` button, or `ctrl-c` in the GPSMan windows), unsaved data will be lost unless the interface state is to be saved (see above). As saved state files will be overwritten automatically by GPSMan it is a good idea to save important data to a file before quitting the program.

- operations that can take a long time are either subject to confirmation (if they can not be interrupted), or can be controlled from a slow operation dialog window if the option on this is selected. This window has an "Abort" button for cancelling the operation and a text box where all the error messages during the operation are collected. When the operation ends the window is closed automatically if there are no messages, otherwise it must be closed manually.
