[function] not aligning with [jit.pwindow]'s contents?

Hi everyone,

I am sure I am missing something indecently simple here.

I am aligning a [function] with a [jit.pwindow] in order to see whether my pattern detection patcher works, and in order to use [function] to manually correct the results after the fact. The [jit.pwindow] gets a 2000x10 matrix.

Now, here is the weird thing. What [function] is showing me seems to be kind of correct, but the line seems to be compressed. I checked by looking at the coordinates of the breakpoints and coloring the corresponding cell in jit.matrix with a setcell message; at the beginning of the image (left side) the colored cell appears _before_ the breakpoint, while near the end it appears _after_ the breakpoint.

I have attached a screenshot for a better understanding - sorry the red cell is so badly visible.

I am SURE that I am missing something essential here - but what is it? :)
