i got a new awesome notebook (Dell xps 15, 2014 edition) with a hi dpi screen and windows8 running. it is fantastic to finally be able to use a touchscreen! but i also ran into some troubles. it would be great if you could take care of those in future releases. thanks!
* the problem regarding the hiDPI screens and Korg midi controllers as described here
viewtopic.php?f=12&t=11353
* removing a column that holds the currently active clip -> the horizontal scroller jumps back to the beginning. this is especially confusing when you are further in your deck and in the middle of "cleaning house"
* setting the incoming and outgoing OSC port accidently to the same value is a nice way to kill Arena and make it unstartable. only fix was to edit the config.xml manually.
* this is an historic bug

* whenever i save the composition the effects panel jumps back to start. as i have to save quite often (cause we have no undo), this happens annoyingly often.
* the fps display (enabled in Output menu) sometimes disappears. can't really tell under what circumstances, it always happens in the most inopportune moments^^. (but obv it is not a big issue.)
