Has anyone else had recent issues with CGMiner.exe?

My RBoxes running the 20+GH/s ASICs stop every so often with the message from Windows saying that cgminer.exe has stopped working. It has been happening so frequently that I wrote a script to automatically close out the message window so it would start running again. I've been having this issue for tha past couple of weeks and I just started having the same issue with my RBox 100 running the 1.6+GH/s ASICs.

I have Windows update turned off so nothing has installed.
