Hi Seppo,

Would you be able to put together a tiny sample project that shows this and e-mail it over? We're probably going to be putting out a maintenance release this weekend so it would be nice to get a fix for this in there.

The latest build of this product (v24.1.0) was released 2 months ago, which was after the last post in this thread.
