-<p>Jalview sometimes runs out of memory. This is because of the way that Java\r
- runs on a computer - what is actually run is a program called a virtual machine\r
- (the JVM) which executes the java instructions. The JVM has limits on the memory\r
- that can be allocated to the java program - and you might need to increase them\r
- if you are working with particularly large datasets.<br>\r
- If Jalview has not explicitly told you that it has run out of memory, then a\r

- working with a larger set of sequences (this might include open dialog boxes\r
- for saving PNG files, or when interpreting the result of a web service calculation).</p>\r
-<p>The way you increase the memory settings for the JVM depends on which installation\r
- of Jalview you use:</p>\r
-<ul>\r
- <li><em><font size="3">Web Start Version</font></em>\r
- <p>JavaWS sets the JVM parameters through special tags in the JNLP file. You'll\r
- need to <a href="jalviewjnlp.html">make your own jnlp file</a> and add the following parameter into the\r
- <resources> element.\r
- <pre>\r
-<j2se version="1.4+" initial-heap-size="500M" max-heap-size="1000M"/>\r
-</pre>\r
- Save the jnlp file somewhere and then - if you start Jalview through your\r
- web browser, point your browser at the file's url, othewise simply run javaws\r
- with the file location as its argument. The file's url is something like :<br>\r
- <pre>\r

-</pre>\r
- If jalview doesn't start up, see <a href="#memsetting">below</a>. You'll have\r

- <li><em>Unix/Windows</em>\r

+<p>Jalview sometimes runs out of memory. This is because of the way that Java
+ runs on a computer - what is actually run is a program called a virtual machine
+ (the JVM) which executes the java instructions. The JVM has limits on the memory
+ that can be allocated to the java program - and you might need to increase them
+ if you are working with particularly large datasets.<br>
+ If Jalview has not explicitly told you that it has run out of memory, then a

+ working with a larger set of sequences (this might include open dialog boxes
+ for saving PNG files, or when interpreting the result of a web service calculation).</p>
+ <p><em>Jalview Memory Usage Monitor</em>: If you are concerned about memory, or think that things might be behaving
+ strangely because of a shortage of memory, then you can check this by enabling the
+ memory usage monitor. This is done by selecting the <strong>Tools→Show Memory Usage</strong>
+ option. Once enabled, the memory usage monitor displays the currently
+ available memory, the total memory, and the percentage free at the
+ bottom left hand side of the Jalview Desktop window's background.</p>
+<p><em>Increasing the memory available to Jalview</em><br>
+The way you increase the memory settings for the JVM depends on which installation
