[OS X TeX] strange behavior

[Nitecki, Zbigniew H.]

I’m mystified by a phenomenon that has been an irritant while creating a particular document, illustrated by the attached files.
The only difference between the two source files is on line 80: in version (a), the page break is commented out, and in version (b) it is present.
In the pdf for version (a), the text coming after the figure is run together (as if I had failed to exit math mode, except that the font is not the math mode font) but when I introduce a page break, the problem disappears.
In the context in which I am running into this, the page break is not a problem, but I am curious what it is about the figure that creates the problem.
I have left the full figure, which invokes the pst-ode macro/program for plotting solutions of a system of two linear (homogeneous) o.d.e.and in fact when I comment out lines 35-52 and 56-67 (which leaves only the commands for drawing the axes) the problem also goes away (even without a page break).

Any idea what is going on, and if possible, how to fix it without invoking a page break?
