custom variables can't be deleted either ...
But I could before this version !!!
I recopied the old version, deleted the tools and copie the new version again over it !!!
But if I trie this with the new version I can't !?!?!
I go to the customize tools menu, select a tool, click on "remove", I get asked if I really whant to, I select yes but the entry is still there !!!!!
