Hi Steve.


I have discovered that masking a movie clip has the same effect as removing

it from the timeline -- it becomes inaccessible and is reset to frame 1

when it is unmasked.  Not sure if you're using a true mask.  But if you are

moving the mc, that means you're inserting a new keyframe, which will also

reset it.  Instead, make a 2-frame mc, frame one with a graphic that blocks

out the counter, frame 2 with no graphic, and place this in a higher layer,

just over the counter.  Then use your tiny button to toggle the "masking"

mc between "conceal" and "reveal."
