It's not so much MPLAB but the ICD2 that's "pausing" things.

Every time you step the ICD2 it has to "download" the state from the
PIC. How much it downloads depends on what you are watching.

Most people new to the ICD2 make the mistake of watching EVERYTHING, all
the SFRs, all the memory, all the EEPROM. This can result in VERY long
pauses.

The trick is to only watch what you need. Just the SFRs is usually
enough, with perhaps the odd memory location.

For the speediest use watch just the particular locations you want.

Oh, and if you're using an HLL, and trying to single step, remember that
one line of HLL can easily add up to dozens of actual op codes, meaning
one single step can take quite a while since it turns into dozens of
actual single steps.
