Hi Fons,

Here's the example you asked for. I may have changed some lines earlier
today but the behaviour is about the same. After running gmake, you'll
have "biodaq" executable. Try clicking, say,
"Help->About BIODAQ->OK". Or try "Initialize Run", edit some lines,
save, start run, stop run, back to initialize run, and so on as your
curiosity takes you :^)

Best regards,
Allister
