(sorry for my english

I have a problem using the pads in combi-mode
I programmed a combination where I also use the Pads. No problem so far.
But: after saving the edited combination the pad assign I used for this combi is also saved in ALL the other combinations. By changing the pad assign in one combi, the pad-assign in all the other combinations are also changed.
programm-mode runs without any problems.
What is this for an error ? Does somebody have a solution ??
thx & regards,
Miguel
