Everything seemed ok except loading images. The console showed an error about the library libpng. None of the bult-in examples displayed images. How was running smath for linux with mono for windows ? ^^ Edit1: This is the process I followed: -Download TinyCore's iso and install it on virtualbox as explained in this guide: http://www.psychocats.net/ubuntu/virtualbox -Install mono searching on the TinyCore's apptool. -Again search and install Firefox to download Smath for Linux -Open the console and type: "find . -name .tar.gz the find should tell you where the downloaded file is and then you know where to go with the cd command: "cd downloadlocation" then decompress: "tar xvzf download.tar.gz" finally run smath with mono typing: "mono program.exe" -When you are done using Smath, close virtualbox with the option 'save state machine' Edit2: I was told that Puppy runs Smath with images, though the problem Embedded image problem between Windows and Linux (.NET and Mono) remains. If anyone wants to try that distribution it needs to install "libmono-winforms2.0-cil_2.10.8.1" and its 27 dependencies. There are some windows installers here. The beauty of the installers is, you can uninstall them, it doesn't adversely affect windows at all, just like any other software. All in all, for most people Smath seems to run the same in Linux when compared to Windows except the libpng issue mentioned above. However for some of us the problem explained in this post remains, in my case the issues happen in some Linux distro (not in Windows), but strangely in some other Linux, Smath works right (again excluding libpng issues) which suggests to me that the problem is not SMath but Mono (I would say that certain graphic drivers affect Mono's performance and make it fail as explained in this thread).

WAIT WAIT WAIT WAIT WAIT! WHAAAAAT? I believe I have found a problem with the SMath site. Because of this, when I tried an "older" version, I did not. If I go to download for example, 0.88, and click on the 0.88 setup here: http://en.smath.info/for...0-88--12-April-2010.aspx What do I get? 0.95 If I try to get 0.94 from here: http://en.smath.info/for...o-0-94--18-May-2012.aspx What do I get? 0.95 Every version I have tried to download (in the last hour) has given me 0.95. I therefore am unable to try other versions to see if the divide by zero problem is limited to 0.95. Thanks, Kyle It is by design. When one tries to download old version of SMath Studio web-site will find the best version for you automatically! But please look at the download page a bit more accurate: Do you see "Recommended file version" and "Requested file version" tabs there? Here is what one will see when presses on "Requested file version" tab: This is solution I have decided to implement. I hope you understand why it is done so... links to the old SMath Studio packages are everywhere in the Internet and I do not want new users to download old versions of the SMath Studio as we do not have enough time to support different versions of the program. It is much cheaper just to make everything possible to deliver latest versions of the software world wide. Best regards, Andrey Ivashov.
