Hi Bart,
	My program is avialable for download at www.malik13.freeserve.co.uk there
is a column on the left side of the screen with a link to the download page.
There seems to be problems with downloading the seperate user guides zip
file. I will look into this, the program.zip file is ok to download.
Have fun
Tab

Hi Tabraze,

It sounds real good, but is it available for download somewhere?
