Alph NG is being renamed to Alph and will become a free app, with an
in application store where you can purchase options such as the
natural gas compounds and hypothetical capability in the current Alph
NG. Note Alph NG has been removed from the App Store, pending the
approval of the new Alph version.
If you are a current Alph NG customer, you will have to purchase a $1
option from the in app store that will give you these capabilities in
the new release, but in compensation, you will also get the new
distillation tower tool and the Steam95 property package included in
this bundle. This option will only be available to folks who have
previously run Alph NG on the device they are updating, so it is
important that you purchase this as soon as possible to protect
yourself should you need to move to a new device or reinitialize your
current one.
Yes distillation! Alph now can do rigorous two phase distillation
towers and they are surprisingly fast. Check out the revamped Alph
web page and tutorials for details. (http://www.redtree.com/alph).
This will be a $99.99 dollar option (you can't have even numbers on
the app store) for the standard Alph, but will be included as a
standard feature of Alph Jr. Thus Alph Jr. is actually more capable
than the base version of Alph, but it does not have access to the in
app store and so is limited to C1 - C10 as compounds. It does provide
a way for Alph users to try out the column before deciding to buy the
option and might be useful in some instructional situations. Alph and
Alph Jr can happily reside together on the same device.
There are some other goodies too, such as a very simple compressor/
expander tool and a mixer tool, that don't really add new
capabilities, but make life easier.

I did come across one problem that was a bitch to reproduce and hence to find and that was that having double dots in a tower reference (something like #tower.0..p) would crash the program. The double dots were hard to see and of course never entered on purpose, so it was hard to find. Of course I have no idea if what you were seeing was related to that, but it is the only crashing bug I have run into recently.
