cmdButtons walk around in excel worksheet

hello all,

ik placed 2 commandbuttons on an excel worksheet, one is for updating a list, the other is a "reset" button wich clears the whole list.

everything works fine but.. when i do a " print page preview " ( excel is in dutch, so i don't know the exact englisch expression ), the button next to the "print " button, the commandbuttons take other places on the worksheet..they shift to the left, and keep shifting with every " print page preview " until they can't go more left..they keep working, but it's a silly view..

can anybody help me out with this ?

greetings
sven
