# [XeTeX] xetex and graphics: strange behavior

Jonathan,

Did you receive the non-Context examples I sent you on 12/2/04? I think
I called them "Example files for infinite loop in XeLaTeX." My behavior
has been that the file never finishes and once the bad hbox is
encountered I have to kill the xelatex process. I have even gone so far
as to completely remove GW TeX and any traces of a TeX installation and
start from scratch. The odd thing is that the files used to typeset
before I updated. I am curious if anyone with XeTeX .87 has this
problem or is it .88 only. That is the only difference I can see
between my reinstall and prior state. I think I had .87 when I was able
to typeset the examples I sent you.
