LED turns off when jumping to a routine

[plyrathrt]

I have a funny issue I have been dealing with for some time and can't figure it out.

I am using a 16F1829 and have the LED on porta.5

During my startup routine, I have porta.5 setup for digital, no pull ups, the latch register is set to low and the tris register is set for input.

When I turn on a feature on my project, I turn the LED on by flipping the tris register to an output. This lets the customer know that the feature is on.

Now when they press another button, the code does a jump (gosub) to a routine. When this happens, it turns the LED off.

For the life of me, I can't understand why.

Here is my startup configuration

DEFINE OSC 32
PORTA = 0
PORTB = 0
PORTC = 0
