File format change

One of our large customers ran Decision Explorer through some testing processes to check if it was vulnerable to attack. Thousands of tests, and some of them showed that Decision Explorer could have problems with files modified in interesting ways. Mostly you could cause it to hang on loading, and we’ve never seen files with any problems, but they needed more assurance. And so we have promoted the existing XML file import and export to be the primary file format as of version 3.5.

What has changed?

Most people will carry on as you always have. All your existing models (file extension .MDL) will be there and load as before. New models will be saved using the XML based format, with a file extension of DEXM. (This new extension also helps to stop conflicts with other applications using .MDL.) You can save a model using the old binary file format using the file type selector in the file save dialog, if you want to send a file to someone using the old version.

Special situations

If you are in an organisation that needs to use a strictly more-secure version, then we have an XML Only build that will not load or save the binary files at all. (The standard build can also be told to not load binary using a registry change, which is handy for testing or transferring models between formats.)

If you really don’t want to have the better XML file format at all, then you can use a binary only build. We do not recommend this version, and it will be phased out.

Identifiers

The download page for the software has the various versions displayed, along with the previous 3.4 version. When you install, you are shown the version that will be installed. This information is repeated in the About dialog, so you can confirm your installed version.

“XML” – standard version

“XMLO” – a version that cannot read the binary file format at all.

“Binary” – a version that cannot read the XML file format (except in import mode which is not so easy to access).

The Viewer and Demo versions will be updated with the new XML tag too.

Latest update released

It’s worth mentioning that the latest version of Decision Explorer is now available. Updates have been released over time to improve various things for special situations, like a multi-monitor maximise.

The current version is 3.4.0 (build 604)

Decision Explorer update

We have recently made a modification to the concept move and link operation based on feedback from users. Specifically, in some situations clicking and dragging a concept failed to work as expected. This was due to the code detecting the movement, but the mouse had moved outside of the concept area before the concept move was triggered. There is a workaround in the version you have – simply move “within” the concept and
not “away” from it until the concept starts to move, but that is not ideal.

The new version 3.3.2 (build 534) fixes this and is available for download using the same details as you downloaded originally.

Smart Mouse update now available

A new update for Decision Explorer is now available for download. This update adds a new mouse operation mode to allow the creating of links and moving of concepts using just a single mouse button, instead of the older two mouse button mode for moving. Now, when you move the cursor over a concept, the mouse pointer changes according to whether you are on the left or right half of the concept, to indicate the action that will happen when you click the left mouse button.

This allows easier use generally, but also makes use on interactive whiteboards possible.

You will need to uninstall the existing software before you update as we use a new installer. This should be safe though, and if all goes wrong (it won’t!) the old version and installer is still available.
