Samplers questions

Hello again I have a new question about samplers
When I'm in Juggle 1-4 mode and I got the cues that I want in buttons SLICE ECHO CUE PLAY and I want to make a sampler.
This is what I do, is it right?
Press PLAY (I'm in Juggle mode) and when I want start to ''record' I press sampler and press the headphone button from the side I want to record (lights of the headphone start flashing)
First question: When I press the headphone button It will start to record?

When I press it, light from DELAY gets on and when I pressing the CUES you can heard the sounds that you have recorded on the song, some times the tempo of what I recorded changes and also when I press a CUE sometimes it does not record it, to sum up it does strange things...
I was thinking that could be because the DELAY button is on (I did not put it on) and if I press it to get it off, sampler mode also gets off...
It´s not pretty well explain but hope you could understand

Do you think this problems could be for my firmware (1.2)?
Because I do not want to upload to 1.3 until I have more experience...
But if there is no solution I will do it
Thanks people!

do the firmware upgrade, most of the bugs are due to crap of the 1.2 firmware!

if you don't want to upgrade, make your own mapping for your own firmware, as i did.

Thanks mate! but I think I can not do my own mappings yet
Are there any mappings frome Ean or from someone quite similars to the latest one (the one that you can dowload in this website) and it works cool with the 1.2 firmware?

Any ideas?
