Cgview 2.* vs Cgview 3.*
Cgview 2.* and cgview 3.* are developed using Delph and C#, respectively.
Cgview 2.* has history longer than 10 years, so it is stable.
On the other hand, Cgview 2.* have several un-fixed bugs as we no longer keep fixing
Cgview 3.*, developed in 2016, runs on Win.7 and later and the response is quick.
For example, reading in an egs5job.pic of 23.6MB takes 24" and 4" by cgview 2.3.0 and cgview 3.0.2, respectively.
We recommend to move from cgview 2.* to cgview 3.0.2.
