I noticed some similar sounding freezes with Read, and it appeared to
me that the initial fit-to screen-width takes up significant amount of
resources. Of course, I'm not sure that this is the reason, but given
the problems we are having with zoom, it may be one of the
contributing factors (apart from the usual overhead of opening the
file and initial rendering of the pages)
