Drag function disabling button actions within movieclip

Question

I'm building an interactive map and i've run into a problem. The map is draggable and I have a start and stop drag function running as well as an onEnterFrame function which restricts how far you can drag the map. The map is displayed inside of a masked area. On the map is many locations which when rolled over should pop up a little dialogue box with contact info. My problem is that it only works when i've disabled the drag functions. When the drag functions are running the buttons inside the map movie clip all stop working. How can i get around this?
Drag function:
// Start Dragging sequence
map_mc.onPress = function() {
    this.startDrag();
// Stop Dragging sequence
map_mc.onRelease = function() {
    this.stopDrag();
onEnterFrame = function() {
//Restricts player to stage
if(mc_map._x <= -1400) {
  mc_map._x = -1400;
//Restricts Bottom
if(mc_map._y <= -400) {
  mc_map._y = -400;
//Restricts Left
if(mc_map._x >= 50) {
  mc_map._x = 50;
//Restricts Top
if(mc_map._y >= 50) {
  mc_map._y = 50;
Sample button function:
//Distributors
santafespringsDI_btn.onRelease = function() {
distributorLabels_mc.gotoAndStop(11);
distributorLabels_mc._x = _root._xmouse + 10;
distributorLabels_mc._y = _root._xmouse - 80;
santafespringsDI_btn.onRollOver = function() {
distributorLabels_mc.gotoAndStop(11);
distributorLabels_mc._x = _root._xmouse + 10;
distributorLabels_mc._y = _root._xmouse - 80;
close_btn.onRelease = function() {
distributorLabels_mc.gotoAndStop(1);

Answer 1

I got it working, but i managed to break it again. I think this is why i was having difficulty with your suggestions earlier. I added a bit more to my code and broke it.
I have a movie clip full of captions that i assign to each location. the button will make the movie clip jump to a certain frame revealing the appropriate caption for the appropriate location and then on rollout go back to the first frame of the movie clip to hide it again. Adding this functionality in stopped the dragging and I'm wondering why it did and how i get around it?
The button code i added to activate the caption movie clip was this:
btn.onRollOver = function() {
    captions_mc.gotoAndStop(11);
    captions_mc._x = _root._xmouse + 10;
    captions_mc._y = _root._xmouse - 80;
btn.onRollOut = function() {
    captions_mc.gotoAndStop(1);
