ion3 problem

dear all, I've been using the `ion3' window manager (currently: 3rc-20070608) for quite some time now but have encountered a new problem with the above mentioned release which was not present before: tagging windows (`MOD1+T') apparently works (the checkbox in the title bar appears), but a subsequent `attach tagged' command is ignored (both, from the menu as well as via `MOD1+K+A'). on the other hand, attaching a window via `MOD1+A' and selecting the name still works OK. before getting bullied on the `ion3' help list my question is: can somebody confirm the above described failure of attaching tagged windows? thanks, joerg
