thanks for your feedback.

I've indeed found a problem in Remote Buddy where it may not release 
some of its allocated memory immediately or sometimes not at all (or 
rather: Cocoa won't, for whatever reason). Anyway, adding the two lines

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

..

[pool release];

around the main event handling code fixed the problem. So this will 
be fixed in Preview 6.

Cheers, 
Felix
