Micro-Cap and other OSs (non Windows based)

For some years now I’ve known this product and recognized it as an extremely
valuable asset from the very beginning. Recently, I stopped using Windows XP and
switched to Ubuntu (in addition to 2 other linux-based distros. Now, I’ve been
browsing the web for information on running your application under a linux OS
and didn’t find anything on the subject.
Are there some of you using linux and being able to run this application
within? If the answer is no or there’s no answer at all, may I ask for another
application capable of doing most of the things Micro-Cap can but under linux?
Thanks in advanced.
