Oh well it's fixable, but I'll need to investigate for that, I'll probably do it later (if ever rain comes back to France it will vastly increase the chances to see that happening !).
And for the warning, those following raine know the real raine remains the 32 bits version, although I thought the 64 bits version was now totally compatible, but raine is all about crazy optimizations and assembler, you loose most of that in the 64 bits version.
Don't worry, it will be fixed, but not now...
