If you have not updated to version 3 of Xbench, now there is yet another reason to do so: the most recent build of the tool (build 1136) adds support for SDL Trados Studio memories (.sdltm files), so, if you were accustomed to convert them to TMX format just to be able to search for terms in them using Xbench, you no longer need to do so. You can download Xbench from Xbench.net. If you download version 3, make sure to choose the correct version for your operating system: there are both a 32-bit and a 64-bit editions of the tool.
Xbench freeware version (2.9) is still available, and still useful, but ApSIC is clearly adding value to the new commercial version of their terminology management and translation QA tool.
If you need an introduction to Xbench, you can download one from this blog (click here): the intorduction is now a bit out of date, as I had written it for the previous version of the tool, but still touches most important functions.
