Bowrap has help built in. Most dialogue boxes have a ‘Help’ button; clicking on this will bring up the relevant help page.
The program is also designed to be tolerant of mistakes. Try exploring by clicking and double-clicking on things. Clicking with the right mouse button is also useful; it will often up a menu suitable to the context.
If you’re still stuck, then ask me. Contact details are on the ‘About’ dialogue (click on the Options menu). Or you can use the form below.
