[NTLK] QuickFigure Pro observation

I don't have Pro, but I've seen QF Works spreadsheets get corrupted 
and no longer usable.

No, I don't know any way to recover.

I've not seen the problem since I decided to keep Newt's spreadsheets 
relatively simple, small, straightforward.

I've not tried to calculate, but I suspect a QF formula has a 
relatively low capacity to keep track of links to other cells, 
especially ones also containing formulas.

Or it may just be a limit how many formulas of a given complexity QF 
can handle in one sheet.

Free system heap and RAM are obvious limits also, but I suspect QF 
sheets don't usually get corrupted by running out of memory; the 
input that exhausts memory just fails until one frees up more.

Bottom line: when pushing QF's limits, duplicate or back up frequently!

As an example what QF Works CAN handle, what I suspect is my most 
complicated successful spreadsheet has about 50 formulas on about 25 
rows. Each row has the same two formulas referring to adjacent values 
in the same row. The first formula is a simple multiplication against 
the value of the first spreadsheet cell, the second subtracts another 
value from the multiplication cell and then divides by the 
multiplication cell.

Happy Newtoning!
