Plugin prompts unresponsive during Startup

DAW: Mac Mini i7 2.3, 10.8.2, Cubase 7

When I open a project and Play try to asks me where some samples are, the prompt would come up but clicking on the buttons will not respond. Hence the whole thing just get stuck there.

Is there any solution to this?

I’ve had this happen to Play, SSDSampler so far. So it’s not a single plugin problem it seems!

Has anyone experienced this or even better have a solution for this without losing plugin settings?
