Hi,  
for the support just to be aware of, the trace sets reflection/refraction…  
one has to completely stop a dn restart IPR for them to update.  
Simple refreshing doesnt works.

Thanks for the pointer, I completely missed the trace sets. Will implement them.

Best regards,

Perfect! i will keep noting down the little thing i spot and then create a thread will all of them at the same place.  
It must be bloody difficult to keep track of the forum and loggin down the errors/pointers

It’s not that hard to keep track of things 🙂 Just keep them coming.

Bear in mind they have an internal bug tracking system where these sorts of things get logged in (propably with the thread of the user pointing it out for later answering there if it’s fixed)
