A4Tech Mice work unproperly on Mac

I have just been presented an awesome mouse G9 500F from A4Tech production. I have faced problems with this stuff on my macbook pro, handling SL 10.6.8, probably due to the lack of compatible official software and supported drivers from A4tech side. The mouse runs well as far as I don't bring on heavy-process programs, games as for instance. There I have freezing and extra-inertia effects, so it doesn't go smoothly at all, all those altogether brings me problems with pointing on in shooters and so on.
Going to the official A4tech site I haven't found any luck with finding any Mac's support note either any forums dedicated to their products.
What I have now at the moment is a so-so running mouse which sometimes places the cursor randomly away from the current position and mouse extra buttons with no response by clicking on those.
There is program hung on their website WirelessScreenCapture.exe supposed to let them be programmed within 16 functions on 1 clicking button. My guesses are this soft carries all the necessaries including drivers for correct work of this mouse.
Any idea about how I can import this software to the native Mac OS environment? Using Crossover didn't help a lot, as it runs this program trying to be installed as it would be run on Windows.

 

It is already a new mouse, that makes it pity.
