BUG:	When using 'fixpix=yes' in CCDPROC or using the FIXPIX task on a
	a single long list of input images in one execution
	the error 'ERROR: 757 ' will occur.  This error
	means that too many files have been opened and not closed.  This is
	caused by a bug in accessing the mask that fails to close the mask
	after each image is finished.  The limit is about 58 images
	when using a text file description of the bad pixels and 116
	images when using a bad pixel mask (a .pl file).  The workaround
	is to break up the processing into smaller sets of images.
	If using a text file bad pixel description one can increase
	the number of images by converting to a pixel mask file using
	the task PROTO.TEXT2MASK.

STATUS:	This will be fixed in future releases.
