Im not asking for native linux version — Im understanding complexity and difficulties of such thing. Im just pointing to some weird and unusual mouse handling issue. Which points to some possible crutch in code, which probably can be straightened for sake of windows users too.
Its very hard to write such code, which would produce that problem, even intentionally. So probably there are some bug in program, which emerges in wine environment with that issue, and with some other flaw on windows.
