Matrex

Saving the settings of a project raises the exception:

matrex.file.FileWriteException: The project file project.mxp in
/home/andrea/prj/matrexjruby/jrubytestproject already exists.
at matrex.file.ItemsFileSaver.saveProject(ItemsFileSaver.java:47)
at matrex.item.Project.saveProject(Project.java:1239)

and the settings are not saved.
Workaround:
Edit manually the project.mxp file in the project's directory. It is an XML
file with a content of the type:

<?xml version="1.0" encoding="UTF-8"?><project isDebug="false"
name="popcolorado" useThreads="false" isDebug="false"/>

Just change the attribute you want to change ( useThreads or isDebug) to
"true".
