Costa, help me understand this. Trail mapkey should "call" ptrail mapkey. I do not have to type it after trail mapkey is pefromed? I am busy right now and I do not have time to investigate this but i will get back to you as soon as I check it.
The way I wrote the script, you don´t have to call the mapkey "ptrail" manually, it´s automatic. But, from the info you gave to me, that isn´t happening in your computer. It seems that for for reason, the script calls the first mapkey again ("trail"), it loses the character "p" somewhere in the way.
If you want to break the loop, rename the mapkeys as I suggested, and then it will work in two manual steps:
1st - Call mapkey "t1" to create txa file
2nd - Call mapkey "t2" to play txa file
