Hi all. I'm using Draftsight Professional 2018 x64 SP2 with Windows 7 and the Dynamic Zoom function using the mouse wheel has stopped working properly: The degree of zoom achieved relative to the wheel movement has changed drastically, so that many more turns of the wheel are required. Also, there is now a lag between moving the wheel and the drawing view changing. In all other respects the mouse works correctly and the scroll function works fine in all other applications. Our IT support have checked the mouse and graphics drivers and DraftSight has been removed and reinstalled. I use this function a LOT so my productivity has been severely affected.

I've searched in vain for any option to adjust the sensitivity of the wheel, both in DraftSight and in Windows.

Please does anyone have any ideas? Many thanks.
