FM8.5 Runtime and IE7

[Zero Tolerence]

I've came across a problem. Every computer in our company that Runs IE7 cannot keep filemaker open. It opens once, and runs fine, but if the minimize it, or shut if off, it will never open again. (Until you reboot, then the same thing happens.) This seems to have happened as soon as we upgraded to IE7. Anyone else have this issue? Anyone else willing to give it a try so we can make absolutley positive thats the issue? It only happens with a runtime.
