Problem with a converted office 2003 file with user defined functi
 

I have a file with user defined array functions. If I just open the file in
excel 2007 I get no problem working with it, but if I record it or convert in
excel 2007 format and reopen it, it starts slowly calculating ending up
crashing after a while.

I have cleaned every kind of conditional formatting, so it is only related
with macros or user defined functions.

I can send the file if necessary.

I have to admit that the programation is not the best skilled one, but well
it works fine in Excel 2003, and even if open without recording in 2007.

Can somebody help me
