evermore and post tease conflict with calendar

has anyone other than me noticed that the ‘post tease’ or ‘evermore’ plugins cause calendar conflicts? for instance, if either the two is activated (only did one at a time, both had same effecs) the stories could be expanded by clicking on the ‘more’ link, but calendar entries got an error message ‘post can’t be found’. by process of elimination i’m sure it’s these plugins that cause the conflict so i just deactivated and chose calendar instead. any ideas on resolving this would be great as they’re a good idea for long posts.
