Problem after xml update; xml loaded infinte scroller

[josepilove]

i have some code that moves a movieclip container(mC) left to right in an “infinite” fashion. The container is populated with image via xml and i have two categories with different xml files for each.

When i initially load the swf, everything works as though it should, the images scroll left to right infinitely.
When i switch categories (go to frame 2, removeChild(mC), return to frame 1 with variable set to other category), loading in a different xml, the scroller no longer works. it registers that i want it to move from side to side, but it seems to be governed by something else.
If i try to switch back to the first category again, the same thing occurs where the movement is broken.

Does it have something to do with garbage collection not occuring to clear out the values of mC and its contents?
