Simon,
Now I have the same freezing problem with another XLSX document.
Follows the file where the problem occurs.
The freeze problem occur when I tested this call in a application made specificaly to reproduce the problem (a little windows forms application), on another test with the same xlsx file in complete code of my program, using a multi thread setup, the LoadFromStream function doens´t freeze but after your return I get a crash in my application caused by Spire (I think that this occur in a background thread used internaly by Spire, because I can´t catch this exception with a normal try/catch or with a global exception manner).
