Perhaps you set a special software for the mouse. Try it to delete.
Whether there is this effect when using mice of different vendors?

Hi,
I have two Logitech Mices. Independent of which Mouse is used, the Scroll Wheel of both mouses are only working on Workplace 1!
this means working with the mouse on workplace two works with the pointer, but scroll wheel is operating on workplace 1.
Any idea? Do i need to use two different Mouse Vendors or is there a workaround?
Thanks.

with this software, i've leaned that gaming mouse specially doesn't work. ordinary pnp mouse with just a right and left click and mousewheel works.
