Just wondering which one to use.

Started with 3.041( threading didn't work otherwise seemed solid for my use)
*(but have a version in which threading works that satisfies my needs but still lists as 3.041)
3.042.003 ( have display problems / won't zoom in enough to see the cutting )
3.042.007 currently listed
3.042.008 was listed but removed ( downloaded it but never installed it )
Hm....... going back to *3.041 unless 3.042.007 has some advantage.
What's the better of them all?
