you can't just right click a condition and click toggle condition. it won't work, you first have to select the condition with a left click, even though rightclicking highlights it as if selected. It's the same thing for copying(as in copy/paste). This is worse because when you copy it seems to have worked, but you'll be pasting whatever was previously in the clipboard
just tested this on latest version. no longer happens with toggle, but still happens with copypaste
