...(I intended to get a picture of Pauley perrette pointing at you with both hands, and the same text, but... i couldn't find it. That one would have been better. Who ever argued with a cute girl...)
Yeah, she's kinda cute and scary at the same time. I'm not sure what I would think if she was coming toward me pointing with both hands - I might well run away 
A couple of important things to mention about the Software:
Be aware that there is no SAVE, CONFIRM CHANGES or UNDO
To clarify, the only undo is if you type in a text field, you can go the the edit menu/undo. Because it's a database, save is done automatically.
However, you can duplicate a composition before messing with it and you can also export all your compositions for safe keeping.
Be aware of using the mouse 'wheel'
If you are viewing all your compositions (Scripts/Show ALL & Sort) you can use the mouse wheel to easily flick through all your compositions - If you start editing one of the compositions then it can be too easy to accidentally move the wheel and not realise that you are editing a different comp. Been there done that 
Therefore, if you are editing a composition, it's better to select it from the comps list and you will ONLY be shown that composition - problem solved.
The "Make a Mix of" box
One interesting and useful thing that can be calculated, is the scenario where you only have a certain amount of units left of a particular chemical. You can simply adjust the total units until it matches.
Example:
I want to make a mix of DE's but I realise I've only got 5 units of Al(200 mesh) left. I can simply adjust the mix total until it matches the amount of Al that I have:

As you can see, all the other Chems are automatically adjusted to suit. Handy and easier that using a calculator to work out new ratios or percentages. etc.
ADDITIVES
I can't really remember why I introduced "Additives" or if it was really necessary but you can see in the above comp the NCL was used as an additive, ie. Added after the main composition, much like you would add H2O. Well, that's the best explanation I can can up with - if it doesn't make sense, then don't use it.
[ERROR] I just noticed that in the Additives section it shows "grams" it should be units - my blunder. I'll fix that if and/or when anything else needs to be updated.
IN SUMMARY
I've seen that a few people have downloaded this - and hopefully it's of some use. Please use it, check it out and compare to your other methods and reply here if there are any obvious issues (like the one I've just noticed above).
I cannot STRESS this enough! Please give feedback good/bad/indifferent. It's still the holiday season, so I'll leave it up for another week or so, otherwise I'll have to remove it. I don't wan't this software to stay on this forum if there are problems with it.
After-all, I have my good reputation to uphold.
