How to end Curtain mode when using Apple Remote Desktop?

Normally Curtain Mode drops when you stop controlling the system. But there has been a persistent bug in ARD since the Curtain Mode feature was introduced that in some cases doesn't drop Curtain Mode. Kickstarting ARD, if you have access to the system via SSH, often works, but if not, or you don't have SSH set up, restarting the Mac is the only way I know of to get Curtain Mode to release.

Here's the basic skinny on kickstart:

Dear community,

this issue annoys me for years now (ever since i use ARD) and is why i never use the curtain mode since it visibly demontrates to your users how crappy admin tools for OS-X are - each time it fails and you have to ask your users to restart the machine - very embarassing. That those same admin tools (ARD here) also have very cool features is by contrast nothing that users can witness...

With the advent of ARD 3.7 this one was the first thing i checked, just to learn that STILL this is not sorted out and APPLE feels perfectly fine in just recommending to use curtain mode in a silly and "workaround"-style fashion (http://support.apple.com/kb/TS2401).

Why on earth can't they at least implement the restart of the ARD-agent into the logoutout procedure - if i can do this via ssh - if they obviously can't/want to fix this issue thoroughly?

It's not just this issue that bothers me, it's how it is dealt with and what this seems to tell about APPLE's attitude towards professionalism.

So please APPLE listen: there are (still) some admins around out there who would like to work seriously with your products! Not just fix this issue, but also support the Mac professionals out there better which maintain your products. It's not just all about iTunes...

Best regards...

It's been clear for a long time that ARD is a low-priority product for Apple and that third-party solutions are a much better, if also much more expensive, choice for enterprise-quality support.
