DO silently crashes when using CTRL and Mouswheel in edit-mode (found it while trying if this shortcut is supported).
I can confirm this happens.
Also confirming. Put DO Version 10.0.2.0 into customise mode, place the cursor on an empty space in a lister, hold down Ctrl, move the mousewheel backwards and forwards, and DO crashes. Not that it matters at all to me. (32-bit Windows 7 Pro SP1, fully updated, on an HP desktop.)
