thanks for the info. for the test they did, i tried it first with a manually operated machine. and then they had me use an automatic machine which showed different things asking which one is clearer. and then some one talked to me asking for things and had me do the same machine with simpler things.
oh well, at least the headache is gone for the meantime.
Sounds like they were very thorough.... I'm glad the headache is gone in the meantime!!👍😀
