Yes, it still happens in 7.18. When the window receives focus the message I get
is WINNLSEnableIME hwnd 00010102 enable -1: stub, and when it loses focus it's
WINNLSEnableIME hwnd 00010102 enable -1: stub. The GOG installers are really
buggy with Wine, most of the time alt+tab doesn't work with them but sometimes
it does work, restoring the window from the task bar sometimes work but most of
the time it doesn't, even minimizing the window by clicking on the task bar
icon doesn't work all the time, there isn't any obvious logic behind all this
weird behavior.
