title: excel udf being called too many times
body: <p>I have a excel function defined in a module which is called a total of two times as a worksheet functon. However when I do a shift+f9 and place a breakpoint on the function, i noticed that its getting called more than twice, around 5 times. This function however is not being called anywhere else, both programmatically or in any worksheet except for the two cells i mentioned above. </p>
  
  <p>Furthermore, when I look at the call stack when execution hits my function, it shows just my function being the top level call. Any help regarding what may be causing this? Thanks.</p>
