Thank you for this. Would you mind sending me your file, so we can examine it? This will help us analyse and hopefully fix the problems.
But just to quickly touch on your questions:
1) Yes, making the lasso less taxing on the program is important. We will look into this.
2) We already have a system in place doing that. But it needs more optimisation.
3) I do not understand why this happens, no. This is the main reason we want to have a look at your file, to give us a clue.
Please send your .ap file to my email adress. Just reply to the email you got from me with your activation key.
Thanks a lot!
