IOLMaster — General Operation.
For safety reasons, the IOLMaster operating system is not accessible
the user and works in the background.
All attempts to modify the IOLMaster operating system
are strictly prohibited. In particular,
deactivation of the Windows firewall is not permitted.
Windows operating conventions apply to the user interface
of the IOLMaster software. This relates to utilizing a
mouse/touch-pad, the use of icons, dialog boxes and
menus, confirmation by double-click, etc.
The IOLMaster software does not support all Windows key shortcuts. The special
Windows keys that exist on some keyboards are ineffective.

The IOLMaster does not support the submission
of generated error reports sent to Microsoft.
