3D Connection mouse not working with Sketchup Pro 2015

Hi everyone
I have just downloaded Sketchup pro 2015 and it’s working fine but my 3D connection mouse won’t work. Anyone else had this problem?

Not sure if this is applicable, but my mouse started acting up and I realized it started after I changed my Windows desktop theme. I don’t know why this would cause a problem, but when I reverted back to the previous theme, the mouse worked fine.

I use a space mouse with SU15 with no problems at all. Have you uninstalled it and re-installed it (mouse driver, not SU) ?
I was using SU14 with my space mouse, then upgraded to SU15 but didn’t have any issues at all, it simply continued to work.

Thanks I will try this.

I use a mac, but thanks for your reply
