Starting to see a series of errors where the Add-in suddenly seems to stop responding. After closing and reopening my file a number of times and verifying that characters are logged in it finally gave up the ghosts and showed no characters logged in.
Now I might get one, maybe two characters logged in before the character selection pop-up stops responding completely (likely an ESI issue) before I have to just close the ESI window. Subsequent attempts to log in a character result in “Error 12007 - The operation failed because this add-in already has an active dialog” even though the dialog was closed. Only option is to close the file and try again.
