When I open an Excel spreadsheet (.xls or .xlt) from either windows explorer or
from the File->Open dialog of Calc, the buttons are not connected to their
original macros when Calc finishes its import.  I should note that I have my
macro security set to medium and I responded Enable to the pop-up about macros
in the document.  Setting macro security to low didn't change anything.

I will attach a copy of the spreadsheet.  Your QA team has my permission (I'm
the copyright holder) to use this spreadsheet for testing/assurance if they so
choose.  It has a fair amount of macro processing in it and uses multiple
sheets.  They can contact me via email for instructions on how to use it.
