Love this mod man keep up the good work! Two things to mention. 1) I had the same issue as others using the cut throttle command setting my throttle to 50% not zero. I found that the button actually resets my throttle to whatever the keyboard set the throttle to last. Because stock KSP now sets the throttle to 50% at take-off, pressing the "cut throttle" button on my controller sets it to that, 50%. I found an easy fix was simply to lower my throttle to zero using the keyboard before I took off. I simply press the "x" key on my keyboard and then the controller "cut throttle" button performs as expected. 2) This one is a little more serious. Whenever the GUI is open, my memory usage continues to increase until the game crashes. I noticed this because I flew with the presets GUI open for a while so I would not forget the controls I had mapped. The game crashed a couple of times due to over memory, and I'm fairly certain I've traced it down to the GUI being open. I re-tested it on a vanilla KSP+AFBW and got the same problem. Here are my specs: Windows 7 64-bit 8 GB of RAM KSP 0.90 -force-opengl Xbox 360 Controller AFBW v1.4 installed via CKAN Output_Log.txt Steps to recreate: Load a craft Allow memory to stabilize Open GUI interface from toolbar When I do this I can watch the memory usage for KSP increase in windows Resource Monitor. Closing the GUI immediately stops the memory increase, but it does not return it to pre-GUI memory (i.e. each time I open the GUI KSP utilizes slightly more memory). Re-opening the GUI again causes the memory to increase until it is closed again. Thus, I have a limited number of times to open the GUI before I crash KSP. Hope this helps. Let me know if you need more information.
