Hi all, I am seeing quite a number of reports from users of my software where on the console, there are errors like the ones below, but I haven't been able to reproduce the problem here:
2012-02-21 23:49:05 +0800[3]: kCGErrorIllegalArgument: CGSDeviceCreate: Invalid window
2012-02-21 23:49:05 +0800[3]: Failed to create window context device
2012-02-21 23:49:05 +0800[3]: CGWindowContextCreate: failed to create window context delegate.
2012-02-21 23:49:05 +0800[4]: _initWithWindowNumber: error creating graphics ctxt object for ctxt:0xed23, window:0x0
2012-02-21 23:49:05 +0800[5]: Feb 21 23:49:05 nomato-iMac.local NovaMind5[5658] : Failed to create window context device

Some people are also getting this, which I believe might be related:

Any ideas what to look for to try to get to the root cause of this?
