Someone broke the JavaScript that powers one of the more important aspects of my job, and also one of the more important aspects of the legal department's job as it relates to account contents and subpoenas; and apparently no one noticed until now. Now I get to scrounge around in the code, figure out which calls are failing and why, see if I can put together a patch that will work across all accounts or if the repairs would account-specific, find a workaround for all of the cases I've already closed, find out who owns the tool that this code is a part of, send them a copy of the patch, and hope that they actually bother to fix it.
Edit: Heh... it's worse than I thought. It appears to have been a conscious effort by someone (probably a vendor, because FTEs know better than to pull this kind of shit), to lock things down so they only work in IE a screwup by someone who didn't know how to appropriately call and XML document in Chrome, Safari, and Firefox; because IE 8 is different than IE 5, 6, and 7. That'll be great for all of my customers except the ones who use Apple computers. At least now I can tell most of my customers that we only support IE 8; but that doesn't bode well for a company that's been sued for anti-trust as many times as we have.
