Putput, thanks for your efforts in getting us all closer to having this working correctly.
Biggest problem that I see is that you can't use the normal button to bring it out of fullscreen and then get back to the main screen whilst leaving it running...........
I usually just setup the trip and then minimise it and let it prompt me over my music, but in this case your only option to get back to the main screens seems to be to close it which isn't ideal.
I don't understand why Centrafuse doesn't want to work with this, I can only assume because the application won't let it resize down to allow the toolbars to be visable, but I'm sure they could recode the external application stuff so it put scrollbars in if the window won't let itself be sized that small, then they could allow the usual functions.
Thanks again though for your efforts, it's a step in the right direction.
