`kazuma thats because of loops over low ... darthreven i donno y u used loops and made this alias od 20 or 25 lines...it can be simply done easier,shorter,faster than that...

alias mort.mp3.writetolist {
if ($dialog(mmtm)) {
var %num 1
did -r mmtm 12
while (%num <= $findfile(%mort.mp3dir,.mp3,0)) {
write mp3list.txt $findfile(%mort.mp3dir,.mp3,%num)
did -a mmtm 12 Track: %num Name: $remove($findfile(%mort.mp3dir,.mp3,%num),%mort.mp3dir)
}
inc %num
}
else {
var %num 1
while (%num <= $findfile(%mort.mp3dir,.mp3,0)) {
write mp3list.txt $findfile(%mort.mp3dir,*.mp3,%num)
inc %num
}
}
}

that alias is really messed up , it hold alot of uneeded identifiers,variabled,commands u should have simply done it using

alias mort.mp3.writetolist {
if ($dialog(mmtm)) {
did -r mmtm 12
var %x $findfile(%mort.mp3dir,*.mp3,tempo,write mp3list.txt $1-)
loadbuf -o mmtm 12 mp3list.txt
}
}

that will load all the filenames without the path to the file mp3list.txt then loads the file into the list box so fast. u can then play this mp3 by /splay $findfile(%mort.mp3dir,$did(12),1). you dont need to use $remove(x,%mort.mp3dir) to ur knowledge $nopath() do the same and its the original for that purpose. briefly this is a 1000 lines snippet while it can be 600 lines snippet.
