Hi,

I've the following problem on OS X 10.6 and later:

My document based app (reads some small and big (150MB or more) ASCII files to 
process data, I'm using the method:
readFromURL:ofType:error: and returning canConcurrentlyReadDocumentsOfType: to 
YES.

When trying to open a bigger file the "Open File Panel" (window) gets 
unresponsive (stays open)  for several seconds.
For the smaller files the Open File Panel just disappears after clicking the 
"Open" button, as expected.

Are there any solution to hide immediately the "Open File" panel after clicking 
the "Open" button in an document based app ?

Any help is greatly appreciated.

Gilles
