We are aware of several "unfixable" viewing problems caused by browser incompatibility, bugs in software, or our own incompetence (hey, we are organic chemists, not computer scientists! ). We try to make these pages accessible to the largest audience possible.  That means many browsers, many operating systems, many headaches...

We would appreciate it if you report problems to us. The more details you give us, the better the chance that we will be able to correct these problems, but we offer no promises.  Please first read the list of known problems and then, if your problem is not on the list, submit the form below (it is anonymous, and we will be able to respond only, if you provide us with correct e-mail address).
