MarcoF, mate
It's known behaviour of PP since very first beta release...
To understand why it works like this, you should imagine that all data transfer between PowerPack and imagevue app is just like a really thin strand.
Just impossible to cover every single case without making a deep invasive operation to the imagevue files. This thin connection strand would be probably breaks down at some imagevue update.
I decided to make PP "human friendly", automatic, with simple installator and management panel, integration to imagevues admin panel.
Even for those of you who have never seen before any script
The imagevue script is very hard to modify because its modular structure. With a little distanse, the PP may works good with a few more imagevue updates. But need to know of its few limitations, like this one...
Cheers!
