Usb stick problem

I have a 32gb Kingston usb stick(flash disk).
I do not know why, but this stick does not seem to be 'compatible' with my mbp, osx-lion.
When I want to eject it, several times I have to 'force-eject'. Not always though.
Other times I try to empty the trash, with usb stick connected to mac, which means that the trash can has also usb stick deleted items, and my mbp crashes(halted - I have to restart mbp).
I tried to format it, I used disk utility also, I formated in pc-windows as well, I tried so many different things. No convenient result.
It seems that something is wrong and I do not know what it might be.

I use other usb sticks with no problem.

I use this stick in windows without problem.

I have 'blueharvest' pane installed in my system.

I cannot believe that this usb stick is faulty, because is Kingston, and I use so many Kingstons without problems. After all, if there was a problem with the stick, wouldn't it happen in windows machines too? But I use it in windows without problems.

But something bad happen in this strange relation between my mac and this stick.

Can you help me solve the problem?

 

Yes, one of my efforts was to format it on a pc. But this does not cured the problem.
