# Notes About Running CoHort Programs On Mac OS X

[This information can also be found within the programs: see `'Help : Mac OS X'`.]

## For All CoHort Programs

- CoHort programs usually work best with the latest version of Java. CoHort programs need at least 'Java 1.3.1 Update 1'. You can use `'System Preferences : Software Update'` to get the latest version of Java.
- CoHort programs work better at screen resolutions of 1024x768 or higher. You can use `'System Preferences : Displays : Display : Resolution'` to select 1024x768 or higher.
- Double clicking on a file in Finder will not start one of the CoHort programs. You have to start the program then open the file.
- In the file dialog boxes, CD ROM drives and other drives appear under `'/Volumes'`.
- In Mac OS X versions prior to 10.2, switching windows (for example, from a dialog box to the main window) requires a separate mouse click to select the new window. After that click, you can do anything you want in the new window.
- Choosing `'[ProgramName] : Quit'` quits the entire application without saving your work. Use `'File : Exit'` to exit the current window and see the `'Save Yes/No'` dialog box.

## Notes Specifically Related To CoPlot

- If no dialog box is open, you can pick an object by using Apple click.
- If the CoPlot main window is partly hidden by the dock, you can resize the window or use `'System Preferences : Dock'` to select a smaller `'Dock Size'` or use `'Automatically hide and show the dock'`.
- Leave `'Drawing : Other : Smoothing'` set to `'On'`.Otherwise, your drawing won't look good.
- Leave `'Screen : Automatic Redraw'` set to `'Yes, always redraw everything'`. If you set it to `'Yes, but just things that change'` CoPlot will often leaves 'ghosts' of old objects on the screen.
