Hello,

Upon compiling a VBA Excel 2003 project, I get the message "Undefined
User Defined Type" in an Ok/Help box.

There's no highlighted code line at all to help me find where the
compiler found this.

I'm not using UDTs at all, and, AFAIK, all required librairies are
referenced, and none is maked as "Missing" in the references list.

Any idea on how to pinpoint the souce of this problem ?

Thanks
