I'm experiencing frequent mouse-down errors.
They say Windowserver: Warning: Program "xxxx" posted a mouse-down, blocking hardware events, but did no further mouse activity with various apps in addition to Finder being logged, so the application in-use seems to make no difference. I will be using an application and suddenly the track-pad no longer works. This is will last for about a minute. Sometimes, the front-most window will veer suddenly to the left so that it is halfway off the screen. I will be unable to move it until the mouse-down error ends. Most of the time, I can continue to move the mouse around during these events, but I can't click on or move anything.
Also, sometimes gestures (like 4 finger push up to reveal Mission Control) will be disabled during these events, but not always. This is extremely frustrating and very disruptive to my work; please, help me figure out what is causing this.
EDIT 1: Here is the pastebin link from the Etrecheck report: pastebin.com/tQuPAAVq What is "com.JWVD.cbcache.plist"? (EDIT 2: "mike" solved this question here.) I, also, just noticed in the screengrab I posted that the mouse-downs seem to be happening just about every eleven minutes; not sure if that's relevant or not, but it seems as though a regular process must be occurring to cause it.
EDIT 3: Days of process elimination revealed the offending app to be Numi 2. Numi 1.7.1 does not inflict the mouse-down events for me in Mt. Lion.
