I have my settings configured so that apps don't close unless I long-press on the home button. This was working fine, until recently, when Cydia decided that it would refuse to close down with the long-press. Short press still takes me back to Springboard, but Cydia is still running and the only way to kill it is to respring.
This only seems to affect Cydia - all my other apps do as they've been told.
Activator seems to have sensible settings as one would expect. The only other thing that might be relevant is that I did try Multiflow recently, but didn't like it and uninstalled.
Does anyone have any ideas?
