Good Morning Everyone,
Here is a useful update to this problem for you all. I have asked Apple for a possible upgrade to the Mouse/Tracker Settings to give 'Micro-Movements to these devices but in the meantime, these will help reduce the movements and sensitivity
As mentioned earlier, DataEase 8.2 runs with no apparent problems on a Mac running OXS 10.11.3 - El Capitain. Access to Windows programs is provided through a piece of software called Parallels - my version is 11.1.2. Both the Mac OS and Parallels have adjustments to control the speed of Scroll and of the Mouse Pointer:
On the Mac it is:
System Preferences>Accessability>Mouse and Trackpad>Mouse Options:
Set Scroll Speed to Minimum and Remove the Inertia Settings for Scrolling.
Also change the settings for the Mouse itself:
System Preferences>Mouse:
Set Tracking Speed to Slow
Parallels also has a two-step setting. It creates a Virtual Machine on the Mac Drive. In this case for Windows 10.2.Use the Virtual Machine Settings>Hardware>Mouse & Keyboard:
Set Mouse to: Auto-Detect for Games, Check Enable Smooth Scrolling. DO NOT CLOSE THIS WINDOW.
Go into the Windows Control Panel>Mouse Properties>Pointer Options:
Set Motion to Slow and APPLY Setting Changes.
It does work and makes the Mouse more controllable within the confines of a Screen Form when Designing but I intend to kick this one upstairs to Apple to see if it is possible to really slow the Mouse Scroll and pointer Speeds right down by having another Setting added to permit really slow, precise Mouse/Tablet movements.
I hope this will help others for now.
Kind Regards.
Dave Roberts
