Java

The problem: we wanted to give more memory to Blast2GO running on Windows 7 x64, but we kept getting the error *beep* "Could not create the Java Virtual Machine".

Looking at the makeJnlp.php file that the Blast2GO website gives you, I noticed the max-heap-size line:

If you use Blast2GO on Mac OS X 10.5 Leopard (and haven't been derailed completely by Apple moving Java Web Start around), you might have run into the issue of not being able to view BLAST results in a web browser. Blast2GO even helpfully opens a window for you to choose which browser you want to use, but no matter what you select, nothing happens.
