Hi Michael - No extra prefs here, no networked drives, i am just going to remove Xquartz just incase that's bothering things :)

**Edit: Xquartz removed and the problem persists. MoI was slower to open without it, but once it had been launched, and a few web pages visited, and KeyShot launch etc, opening MoI was back to like 3 seconds or so. The file I/O dialog still suffers though no matter how many times it's used. I am not that bothered, it slows things down a little but it's stable and consistent and that's more important to me.
