Ack - sorry about the prefs problem, people - I'll push out an update shortly. I'm pretty active in terms of updates, so I'll address stuff as I can.
As for the memory concerns - yeah, I know - it's partially why I haven't hit 1.0 yet. Using CoreAnimation has a fairly intense memory cost - and Hyperspaces uses it to a great extent.
If anybody comes across crashes (it is a preview!) just be sure to submit the crash report when you restart the application, or e-mail it directly to support at thecocoabots.com (sorry, I can't post URLs or e-mails yet - I need to post more!).
derekl - no, you shouldn't have waited. The version of Hyperspaces you guys get through MacHeist is an unrestricted version, and you will receive updates as I release them - but only until version 1.0 proper is released. If you'd like to continue receiving updates beyond that point, you'll need to pick up a full license.
