[Wine] sine wine 1.0RC1: 4th mouse button doesn't work

[Detructor]

Hey,

since 1.0RC1 my 4th mouse button on my logitech G5 doesn't work anymore...all games that I've (BF2, Bf1942, CS:S, F.E.A.R) doesn't react when I press the 4th button...what is that for a bug?
And why it haven't been fixed already? (I don't find a bug at bugzilla for this...but I don't think that I'm the only one with that problem)
