Strange ADC behaviour

[MarkW]

Hello

Using a 16F690 @ 1Mhz....simple read ADC0 port and display
on LCD (2.5V +Vref)....flowcode 6

All settings / osccon correct

But when i do a simulation or real test....when turning the pot
at some point i get figures that go over max ADC value of 1023
even in the simulation (4000 / 5000 etc etc)
Printing the ADC value to the LCD (INT type)....so its 0 to 1023

Am i doing something wrong?

Thanx
