Considering for example the "Bars" field in the track list, if you click on it, you are suposed to want to edit it..
However, if just *single* click rapidly - without moving the mouse - on the "top" part of the field (as if you want to edit the value using the keyboard, due to the problem described in the next paragraph), the value is incremented before becoming editable. Same applies for the bottom part of the field.
Also, the way one is suposed to click & drag the mouse to change the value is particularily lame, one flick of the mouse changes the value by huge numbers, while all one wanted was to change it a little.
This problem is tolerable for some values, but say the time stamps in the event window gets resorted with the new value, wich makes editing very challenging indeed.
