Mouse Stutter, Jumpy, Bad Clicking, Laggy

Question

QuickACCESS has been running fine for a long time for moving and controlling the mouse, but recently has become very erratic.

It has been very consistent and usable in the past and is now unusable, and crippled. How do I fix it? What happened?

Accepted Answer

UPDATE (Oct 2014) SOLVED: Please use the following version. All versions past 1.6.1 of QuickACCESS are immune to these types of Windows updates.

UPDATE (Aug 2014): http://office.eyetechds.com/downloads/EyeTechQuickACCESSAACInstaller14.08.19.67.exe This build removes and hides the update automatically.

UPDATE 2 (Sept 2014): Another update from Windows seems to also be causing a similar problem. We are working on tracking it down and patching QuickACCESS to respond appropriately. In the mean time, please do a system restore before the recent Windows Update that is causing the problem.

UPDATE 3: The update that also is causing the issue is labeled as KB2993651. A new version of QuickACCESS is being worked on to address this issue.

UPDATE 4: (October 2014) Two more updates have been identified: KB2943357, and KB2970228. The KB2970228 one is related to KB3000061. New version of QuickACCESS is nearly complete.

Running the following on the command prompt will uninstall the correct Windows Updates, but will not hide them.

wusa /uninstall /kb:2973201 wusa /uninstall /kb:2993651 wusa /uninstall /kb:2943357 wusa /uninstall /kb:2970228

How To Uninstall and Hide a Windows Update

This is caused by a recent Windows update. The update was published July 8, 2014.

We have found it on Windows 7 touch screen computers as of 23 July 2014. It causes the mouse to be very laggy while QuickACCESS is running. It does not affect QuickGLANCE.

To be able to exit QuickACCESS while the bug is happening, you need to hold the mouse cursor down for a full two seconds before releasing for the full mouse click to happen.

Diagnosis: You will notice that any click on the QuickACCESS toolbars and large button dialogs are delayed by 2 to 3 seconds before they respond.

Fix: We are in the process of contacting Microsoft about it. For now you can uninstall the update and restart the computer and it should return to normal.

Navigate to Control Panel > Programs and Features > View Installed Updates:

Find the update referencing KB2973201, and uninstall it. See the screenshots below.
