I have tried 'Canvas.clear' but that is thrown out as an error. I have searched all the documentation I know of but have not yet found an answer. Can anyone Help ?

Please show us the code. Preferably the whole source code.
Create a new folder, copy all the necessary files into the folder except: the binary (exe file), *.bak, lib and backup folders. Compress the folder and send the zip here.

Although I've never used the CLEAR method of the canvas, it does work for me on 1.8.4 Windersssss

Many thanks to all who answered with suggestions. I have since found the answer after doing one or two possible commands trying different words I then tried 'repaint' and lo and behold it worked. !!!
