It is probably linked to the database connection but it is hard to say what or where. I seem to recall someone else reporting something similar a year or so ago and they fixed it by installing a different version of mysql or mamp... maybe try XAMP. I couldn't be sure though because that really isn't my area of expertise. I can tell you that that behavior is not typical and I'm pretty confident it does have something to do with your database or server settings. Have you tried connecting to your live remote database? It would be interesting if you had the same result, because that would at least give you information about where the problem is. If it is fine with the remote database then it is definitely you local database causing the problem, if not then it may be something about Dreamweaver itself on that machine.
