strange behavious on AVR Simulator

Hi all ,

I am using AVR Studio + WinAVR to develop software for ATmega2560.
Before the hardware arives I am trying to get used to the uC by
running software on the simulator that comes with AVR studio.

I have all the 4 UARTS enabled and thier TX and RX interrupts enabled.
When I some tests by a byte on all four UARTS the simulator execution
only hits the ISRs for the first two UARTS and not the others.

Is it a problem with the simulator or have I missed some
configuration , I searched the data sheet and found that if TX/RX are
enabled ,TX/RX interrupts are enabled and the global interrupt is
enabled then it should work.

I will be gratful for any comments
