Simulation not starting in ISE Design Suite and ISIM

I was doing vhdl exercise using ISE design suite, while simulating, I faced several times that when I press start, nothing happen, I see run all displayed in the console, but nothing happens.

after spending some time on this, I found out to overcome this issue, I need to run the synthesize then sun the simulation again, this usually solves this issue for me.
