The crash is being caused during update of standard text (NOT using Sol’s TextBox). This is probably caused by a known graphics card memory leak coming from pyglet. That has been fixed in the pyglet library that we’re now shipping with PsychoPy (the “1.2 maintenance” branch) but it still exists in the standard version of pyglet that gets installed by easy_install. So one workaround would be to replace that lib with a newer version.
The other option is to reduce the use of pyglet text in your experiment. In particular, make sure you aren’t using pyglet text to “update every frame”.
I suspect there is a slight difference in these 2 computers, like a different version of the graphics card driver that handles the memory error differently or a graphics card with more memory.
