Weird Lag When Booting Up Mids

[Muppy]

Every time I open Mids with a "new" (aka an existing build from the last version), it will lag. If I open a build that was previously viewed in Mids, it'll open fine... but then the lag problems return if I open a build using Windows Search, even if I have opened it previously. Is this a common thing or is there something else going on?
