Merge/DeMerge Prompt

Hi,
I using a program that calls Excel and automatically does some calculations - the problem being is that this program is totally automated and because it is so it is supposed to run everything through Excel and export some data - now, Excel promps me to click either OK or Cancel to the merging or demerging of cells - because it does this the program then hangs and waits for someone (me) to click OK to continue, i cannot be there to do that so i need to turn off the prompt or just turn off all prompts im not fussed

let me know if this is possible

Thanks :-)
