I have another fix ready :)
In future I will want to cleanup the code a bit (formatting, maybe some refactoring). I don't know if this welcomed because this will break git history.

The format is 32, the first three data longs carry the toolkit's X time (l[0]), the message's major opcode (l[1]) and the message's detail code (l[2]). If no detail is required, the value passed has to be 0. The remaining **two data longs (l[3] and l[4]) are reserved for data1 and data2**. Unused bytes of the client message are set to 0. The event is sent to the target window with no event mask and propagation turned off.

This change is not mandatory, but should go in this change. It is related to Wine bug, when this bug is fixed it will be required to correctly set parent (if I understand Wine code correctly... :) )
