[Qt-interest] ActiveQt / Qt 4.6 - > 4.7

[Jan]

I am having a weird problem with ActiveQt/Excel I can not solve:

My app exports some database tables to an excel file. This worked great 
with Qt 4.6.3.

I just rebuild my application with Qt 4.7.1 (framework only, MinGW). The 
code seems to work I guess: no crash and the excel file is created, but 
the cells are not updated (I get an empty sheet). I changed the 
path/qtdir as well. qVersion says 4.7.1.
If I rebuild with 4.6.3 everything works fine.

The change log of 4.7 does not mention any changes in ActiveQt.

Would be nice if anyone had an idea what could be wrong here.
