Patch for lotus (resubmit)

[Tony Lambregts]

The attached patch (by Toby Haynes I think) has not made it into CVS and 
I was wondering what needs to be done to make it accepatable. I know 
that it is a hack but it makes lotus work.

Changelog :
        dlls/user/painting.c 
        Hack to fix bug in lotus where keyboard input is not displayed
