Project Explorer View Disappears

[Chao]

Hi,

I have used CubeIDE for 2 years, recently the Project Explorer view disappears occasionally, and I found ctrl-m can recover it, but now it's gone completely, ctrl-m doesn't work, Window->Show View->Project Explorer doesn't work neither.

Anybody knows how to recover it?
