Quicktime crashes on one of my computer whenever it need to perform a function on the internet. This includes if I boot it solo, without booting by opening a file. It will often crash Safari as well. My version of Explorer won't work at all and a believe these 2 malfunctions started happening simultaneously, but not sure. Updating to QT7 hasn't effected it, nor has temporarily downgrading to QT6. Is there a corrupted file somewhere or what?
