I have been using SmartNav for about ten years. First with Windows NT, then Windows 7 and now Windows 10 64 bit latest version. It has always worked well until a few days ago when the slider from time to time becomes completely crazy with erratic movements. The configuration has not changed. I use the same computer for two years and I have not changed anything in my installation in the room where I work.

I can not control the mouse anymore it's total panic.

What to do ?

Thank you for your reply.

Hello artafel,

I recommend to changing the mouse override Delay to 0.0. In windows 10 this can cause the mouse to do an unwanted pauses every now and then, and act erratic.


Please let me know if this fixes your problem.
All the Best,

The mouse override Delay is already at 0.0. This parameter has never changed position. It's always been at 0.0.
There was no change in configuration and environment.
It's really very problematic because I can not use SmartNav anymore.

Thank you very much for your help
