Clipboard regression

[Stefan Dösinger]

Hello List,

This patch from 2005/03/07 causes a Clipboard regression:

http://www.winehq.org/hypermail/wine-cvs/2005/03/0111.html

Whenever the clipboard is used the process crashes with an X error.
To reproduce it just start notepad and right click into the text area:

err:x11drv:error_handler X protocol error: serial=271, request_code=1 -

wine: Unhandled exception (thread 0009), starting debugger...
