What can be the reason for the following warning in console.log:
__CGPixelAccessLockWindowAccess: access lock failed: error 1001.
A quick search in Google shows that numerous applications have seen this issue (including Apple's Software Update.app) but there is no explanation.

Error 1001 indicates a bad argument was passed, so I would surmise that it's a bad window (likely one that has already been disposed). This might explain why when you close some combination of windows it no longer occurs.

Unfortunately, I couldn't tell you where the bug is exactly without a lot more spelunking. If you really want to know, then filing a DTS incident would be appropriate. -- David Duncan Apple DTS Quartz and Printing email@hidden
