Mailmerging from Access to Word

Can anyone help me with the following code?
If I reboot my machine, open the Db and run the wordmerge, A WORD msg pop up with "Do you want to save the changes to letters1?" with a Y/N, cancel option. If I chose yes and then cancel, the word document will open and the code runs ok but, I am not sure that this is good practice as it leads to confussion. I am also trying to eliminate the msg that explains to user that they are about to merge from access to word. I think it will just confuse the user even more. However, If there is no work around, then I will have to live with that. Very greatful for any assistance, Cheers, Steve
