I've found and fixed a number of minor UI synchronization issues related to software-lists when switching systems very quickly (SVN r4842)... I guess and hope it's all sorted out now. I've also added a customizable short-cut for the "check software-states" action (default: F10) which makes it easier to check software-states while "browsing the systems".
