Hey Claude
Thank you for your kind words on JED

The new version of Power Slide (2.0) is a massive enhancement of the current Power Slide Pro version 1.3.1. We are doing away with the xml method as there are too many possible combinations in the new version already and including other methods would be a total nightmare! Power Slide Pro 1.3.1 will still exist and still be fully supported, however it will not include the new functionality version 2.0 will contain.
We are still looking at your issue above and will first test it in the new version before it will go into a stable environment (which will be Power Slide Pro 1.3.2)
Will send you a download link as soon as its available
