Hang problem on Motor control in pic

i done the wireless control dc motor interface with pic. I check the output in Proteus successfully and also i checked in the real time.it works good but after some time it's not responding the control key example when i pressed forward direction it not responded.after some time gap it respond. i also attach my coding..here....

Post full code and Zip and post complete MPLAB project files.

As PIC18F is used, use LATxbits.Latxy instead of PORTxbits.Rxy for output pins.

Why use LATxbits.Latxy instead of PORTxbits.Rxy for output pins.
