Delay in Pro Tools window closing?

[Jimibrix]

I'm finding that when I save and close my sessions, the mix and edit windows go as they should, but the large gray work space remains for like five minutes before it closes. Any ideas? I did add WAVES GTR3, as well as Abbey Road plugins... This behavior began at that point. Now, does this mean I need to reload these plugins? I'm running 10.1 on the 003 fader system, Windows 7/64 bit, 24Gb ram... Everything seems to be working fine otherwise... Also: The plugins do not have to be active on any of the tracks, even an empty session is closing this way.

Try moving the new plugins to the unused plugins folder and open and close a session to see if it is back to normal. If so, move one back to the plugins folder and open and close a session. If normal, move the other on and open and close again. This will at least tell you which plugin is causing the issue.
