[Wine] Kindle failure

[MikeYates]

My Kindle for PC has worked fine in WINE for many months, although the offered upgrade last month did fail to install; I didn't need it anyway. Now it has suddenly stopped working, I think since latest Ubuntu updates, not the 1110, it was fine with that for weeks.
What might this mean?
