I looked at the XLS file that Brett pointed to. If I understand it correctly, the old number for the Reset button is 1021 and the new number is 44600. I'm not sure if I should be using old or new. I tried 1021 and it didn't work, and 44600 is too large for the function call (DoButton function takes a short which in VB is -32k to +32k).
Where can I find the developer's document that Art mentioned?
