will there be a cs4 version for the tool box?
a new Dreamweaver CS4 compatible ADDT version has been released some days ago.
If you have already a previous ADDT version installed, you can download an update from here: http://www.adobe.com/support/dreamweaver/addt/downloads_updaters.html
If you´re new to ADDT and don´t have any previous version installed, the trial version has assumingly been updated to be CS4 compatible as well.
another issue which is critical to me to consider it: is it support other languages? like Hebrew? someone told me that he made an insertion form and it insert Hebrew as all sorts of signs
This issue might rather be related to having chosen a wrong page encoding option and/or a wrong Collation for the database table column which stores the submitted values. Neither Dreamweaver´s own server behaviours nor ADDT will change the entered chars when storing the form values.
