Append_management fails, when run with Python on personal GeoDB outside ArcGIS

Append_management and GetCount_management fails, when run with Python on personal GeoDB outside ArcGIS.

When I run the script below from a toolbox in ArcCatalog, it works fine. But when I run it from IDLE or from a commandline it fails with this errormessage: "ERROR 000732: Input Rows: Dataset Data1.mdb\TestFC does not exist or is not supported"

But if I use file geodatabases (.gdb) instead, it works both inside and outside ArcCatalog. It does not matter, whether I use arcgisscripting og arcpy - if I use personal geodatabases it fails outside of ArcCatalog, but works inside.

I use ArcGIS10.1.

Does anybody have a solution or work-around?

Thanks for answering - in advance.
