After a 10 min test, everything has worked fine on my primary monitor. Oddly, though, as soon as I move it to my external monitor, the program now crashes.
Another side note that may be helpful from a development standpoint: the problem seems to be some conflict with the nvida card (driver up-to-date directly from nvidia).
With the standard installation (prior to adding your ini file) I found last night that if I disabled my nvidia card and only ran with the onboard graphics, everything ran well.
I also tried the opposite, but with that the problems continued (nvidia card only ... onboard graphics disabled).
