With XOTcl 1.0.2 on Windows 2000 I get the "Cannot locate the XOTcl library on your system!" message despite the fact that the library is successfully found. I read the message in the archives on this, but a) the workaround didn't seem to work for me (if I understood it correctly) and b) it seemed like 1.0.2 was supposed to fix the problem (but obviously didn't in my case).
