Possible bugs found in latest CDJ Beta release

Using the latest CDJ Beta release (w/ Access) I noticed that about 4 or 5 of my discs appeared grayed-out in the Library window (At lease their CD icon was grayed out). It seemed as though CDJ was indicating that the discs location was unknown or that that (more likely) CDJ thought that the disks had been removed. I know that at least one of the discs had been played in the previous 5 minutes. In an effort to correct the problem I told CDJ to Search For Discs, Look in All Players, All slots, Look in "empty" and Check for missing. CDJ went through all empty slots in both players and then started on all occupied slots in both players looking for missing discs. The problem is that it never stopped! When it reached the end it started over. A problem with this, of course, is that if you select to Queue discs for later CDDB lookup you will never get the chance because you must cancel the search to make it stop.
