I've released an update to the ZHAO. Like its predecessor, ZHAO-II is a free HUD Animation Overrider. You can pick up a copy here:

Changes from the old ZHAO (copied from ZHAO-II help notecard):
* The notecard format has changed. The new notecard is NOT backwards compatible with existing ZHAO notecards. If you don't feel like re-writing the notecard by hand (and you probably won't), rez the provided 'Notecard Converter' object and follow its instructions. The reason for the change - I think the new notecard is a lot easier to set up. Open the included 'Default' notecard to see the new format.
* Inventory checks - ZHAO-II will warn you if it finds an animation in the notecard that's not in inventory. This will help with typing errors, missing inventory, and so on.
* Up to 12 walks, sits and ground-sits. Why 12? Because I'm lazy, and wanted to fit them on one dialog box.
* As many stands as you want, until the script runs out of memory. If you add too many stands, the script will crash, and then you'll have to remove some stands and reset the scripts. How many is too many? Hard to say, depends on how many other animations you've configured. Use the free memory as your guide - if it gets too close to 0%, you're obviously asking for trouble.
* New options for cycling stands. You can have stands cycle sequentially, or randomly. You can choose the time duration between stand changes. You can turn off automatic stand cycling, and use the 'Next Stand' command to cycle stands manually.
* Easier for developers to build and customize their own AOs. No more scripted texture changes, so you can apply whatever textures you want. The only visual impact of the script will be to set a green/grey tint on the root On/Off prim. Also, the main script can now be controlled by sending it link messages (details in the script comments). So you could design a new user interface and build a new attachment, and use the ZHAO-II core script to perform the AO functions.
* Fewer scripts, which means less load on the sim. Rough tests have shown a 4x - 6x reduction in script time from the old ZHAO.
As with any new software release, there may be some bugs that haven't yet been found. If you notice any issues, please IM me with a clear description of the problem.
I also created a group named 'ZHAO Help' for ZHAO issues. Feel free to join if you're a new ZHAO user who's having problems, or if you're a seasoned user who likes helping out other people.
