fix bugs in ActionScript code.

Project Description:
Hello

I have ActionScript 2 code with 2 bugs.
about this flash:

This flash load main mp3, some short mp3 and show 4 tracks.
short mp3 can be drag on any track.
When I press play button flash play synchronize all tracks and main mp3 (if on first track in 3 second put s1.mp3 - he play that when main mp3 plays 3 second)
Also have effects combobox. If short sample have name s1.mp3 And on first track select effect "bass" - flash play s1_bass.mp3.

first flash load vars.txt and effect.txt
vars.txt have syntax: track1=ringtonesCEFAGBDDBC&samp1=song1&samp2=song2&samp3=song3&samp4=song4
effect.txt:
eff1=pop&eff2=rock&eff3=metal
First bug:
When flash load main and short mp3 - he have event on mouse. if I move mouse on flash - he stop load and not draw tracks.
Need create normal load mp3 files.
ringtonesCEFAGBDDBC.mp3, song1.mp3, song1_pop.mp3, etc..

Second bug: if select effect pop he need play song1_pop.mp3 but he play song1.mp3.
