No dumb questions just......
I don't think there is such a thing as a dumb question. Questions are for people seeking answers; the only dumb question is the un-asked one! We ask questions not because we are dumb or ignorant, but because we seek knowledge. There are however dumb answers.....
To prevent myself from falling into the later catagory, I don't know what you should do. It does sound as though the 'dumb' part came from the previous owner!
