Hi guys,
I'm the author of SpiceRack here at TastyApps... I am very sorry for the disappearing toolbar bug.
The culprit here is not SpiceRack, by the way, but Web Snapper's Safari button. We were made aware of it not too long ago, and a new beta is currently being tested to make sure it is stable. As soon as we are satisfied with it, it will be released officially. Please contact me directly (jean at tastyapps.com) if any of you is willing to participate in the beta testing, and I will get you all set-up.
Unfortunately, we don't have time to look at all the forums out there, so unless one of you takes the time to contact us directly, we might never know, or discover way too late, about a bug... So please, please, please when something likse hits hapens, contact the developer. It'll make for a much better experience for everyone.
Thanks.
