My Devel block is displaying the Performance, Switch Users and Execute PHP blocks as well in the sidebar, making it very unsightly and bloated as well.
I can't see what I could have done to cause that and wonder if it is due to some interaction with some third-party module.
What could have caused that?
EDIT: I hve added the code for the block to low. There seems to a lot of admin-pane-xxxx classes and IDs there, and I suspect it has something to do with Admin menu. I have also checked devel on other installations, and they don't display this behaviour. I have asked a related question regarding how to locate where code for a particular block is being generated.
