Also you can't use trigger buttons (caps lock) for something that is not a trigger (control).
You've been told already - your configuration is invalid, it can not be supported by Wine.
I beg your pardon, sir, but it seems what you tried to make me believe is bullshit. Tested and fixed in 1.3.29, and it worked in <wine-0.9.59, so obviously it is supported by wine. Whether it works because of X server or configuration change or a change in wine, I don't know, nevertheless this configuration (Caps_Lock as Control) seems perfectly valid.
