GMan

When I open WLM, the inbox contains messages and what looks like an open folder with no information. If I click on this "empty" folder, it momentarily shows the from and subject information from an email message above it. This is quickly replaced by "Message could not be displayed WLM encountered an unexpected problem while displaying this message. Check your computer for low memory or low disk space and try again." If I try to delete this "empty" folder, a box pops up with "The selected messages could not be copied to this folder". How can I remove this message or messages?
