Lessen learned: I spend hours, if not days, messing around with disappearing instance-variables, that I kept reusing. Or also a UIActivityIndictor that sometime won't hide, although it should (sometimes yes, sometimes no). The scope of this variables was defined local in the @implementation-section. After putting the vars into the @interface, and adding @property and @synthesize methods, all issues were solved. I think, it's got something to do with the lack if retain on my first approach.
