QuickACCESS is wonderful and does many things very well. Occasionally the mouse cursor becomes hidden. I don't think I used the "Hide Mouse Cursor" button.
What is happening? How do I fix it?

QuickACCESS has a deep integration with the input mechanisms on the computer. To mimic the many different ways that the cursor is used, there are a few different ways that the mouse could become hidden.
Toggle Mouse Visibility
The most common way this could happen is with a false click on the
Scrolling and Set Scrolling Target
Eye Dwell - Parking Space feature
There is an optional feature, turned off by default in QuickACCESS called
Mouse Hook Pattern
Recently QuickACCESS has been modified to handle the mouse differently due to Windows Updates during the summer of 2014. The mouse cursor is hooked and is moved in a slightly new pattern than before. If there is another mouse hooking program running on the computer that isn't expecting that kind of pattern, it could cause an issue. We haven't replicated this in our office yet, but it seems like a possible issue.
Mouse Hook Blacklisting
In very rare circumstances, QuickACCESS gets removed from the mouse hook chain because the computer is under a heavy load and it takes too long to process the mouse cursor. With the start of Windows 7, Microsoft makes this a silent error and it is difficult to recreate or diagnose. Restarting QuickACCESS, or rebooting the computer will fix the issue. In some cases, reinstalling QuickACCESS is an easy way to fix the issue. This happens more on lightweight computers running QuickACCESS, and are also running other programs that are hooking the mouse. There is now a checkbox in the latest beta under the
On older versions of QuickACCESS, a corrupt calibration could cause the mouse to get stuck in the upper left corner. This is unusual, and has been fixed. Please update QuickACCESS to the latest Beta version if you think this is the issue.
Vibrating Hardware Mouse
If a hardware mouse is plugged in and vibrates while it is plugged in, or even if it is sitting on the carpet or fabric, QuickACCESS will detect the movement as hand mouse and stall the eye tracker. To test to see if this may be causing it, reduce the mouse move stall time to zero or turn off Mouse Hooking.
