I have written a midlet, where upon logon, it will switch to another displayable after displaying an alert, I noticed 7650 did not respond to the command of setcurrent( otherDisplayable ) or setcurrent( alert )
such as;
Display.getDisplay(midlet).setCurrent(al,this);

or Display.getDisplay(this).setCurrent(startScreen);

the program works alright on the emulator..

can anyone advise...
