    319 Windows poses some challenges for Java applications (like Flukes), primarily from the perspective of specifying paths. In Java properties files, the "\" character, which is used as a path separator in Windows, is treated as an "escape" character (which means that it has special properties for changing the meaning of a single character immediately following it). The resolution to this issue is to use the "/" character for any path specified in a Java properties file on Windows, rather than "\". For example, "C:\Users\Exampleuser" would be written as "C:/Users/Exampleuser" instead. 
    320  
    321 Another issue on Windows is a long-standing Java bug with the discovery of the user's home directory; the bug itself is described here: [http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4787931]. Flukes provides the convenience of using the Unix convention of specifying a path that is rooted in the user's home directory by beginning the path with "~/". This can cause Flukes to run into this Java bug. If this problem is encountered, it can be worked around by specifying the full path to files, rather than relying on the "~/" convention; for example, "user.keystore=~/.ssl/user.jks" would become "user.keystore=C:/Users/Exampleuser/.ssl/user.jks" 
    322  
    323 Most Windows users do not have X11 installed, which creates some difficulty with the "Login to node" menu option. Flukes has a property that is Windows-specific in the .flukes.properties file, "putty.path". This allows specifying the path to the PuTTY ssh client. It is recommended that Windows users download and install this client, using the full installer provided here: [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html]. Please choose the binary on the line beginning with word "Installer:" 
    324  
    325 Key format differences - PuTTY versus OpenSSH. The prevailing OS used on virtual or physical nodes in ExoGENI is Linux, which expects SSH keys in OpenSSH format. PuTTY has its own format, which differs from that of OpenSSH. The solution is to use the PuTTYGen tool included in the PuTTY installation to generate keys for use with ExoGENI. Directions on how to do so are [wiki:flukes_on_windows here.] 
     319Flukes is written in Java to present the most consistent cross-platform to its users. However there are some differences in default behavior available on different operating systems that must be accounted for. These differences are described in [wiki:flukes_on_windows this page.]
