ESPON HyperAtlas sometimes seems frozen as nothing happens when changing a parameter. Most of the time, your java console will display the log message shown on Figure A.1.

A simple action allows to workaround this bug: simply resize your window!

Figure A.1. Java console: stroke shape error

Displayed log message when the maps of HyperAtlas seem frozen.

The deviations maps may sometimes appear "all in grey"... Just click the deviation context combo box in the parameters panel in order that HyperAtlas takes into account the changes of references.

After several analysis with several datasets, multiple messages boxes may appear. As a Java Applet is loaded in memory for a whole browser session, multiple instances may cause this problem.

The simplest thing to workaround this disturbing behaviour is to close your browser, then restart it.

This bug should be fixed in a next iteration.
