[vwnc] invalid context errors during VW startup on Snow Leopard startup

Hello All,

On an iMac running OS X 10.6.x, I see the following output in the  
terminal when starting vw76nc:

tkimac~/image$ ./startvw visualnc.im
tkimac~/image$ Wed Oct  7 20:49:35 tkimac visual[448] <Error>:  
CGContextGetBaseCTM: invalid context 0x0
Wed Oct  7 20:49:35 tkimac visual[448] <Error>:  
CGContextConvertSizeToDeviceSpace: invalid context 0x0

VisualWorks appears to run operate without error.  It is a new machine  
so I haven't actually done much Smalltalk with it yet to find out if  
there are any problems lurking.  I am wondering if this has something  
to do with Snow Leopard or my startup script or something else.

My "startvw" script is typical:

#!/bin/bash
VISUALWORKS=/Applications/vw76nc
export VISUALWORKS
/Applications/vw76nc/bin/macx/visual.app/Contents/MacOS/visual $* &

Regards,

Edwin

Yes, this seems to be Snow Leopard related. It's probably to do with the startup sequence, and trying to do some operations before the system is ready. And yes, it appears to be harmless.
