Well, I think I may know part of the issue I was facing.
This was my first try using Google docs and of course I tried my budget spreadsheet: a tab for each month, ton of formulas, and auto-populations and calculations on an annual summary tab. ... Well, from what I've seen of the Google doc spreadsheets, it is B.A.S.I.C. spreadsheet 101. Doesn't handle 1% of what I normally do with them. It appears that I have a file that's just too robust for the type of "free" access G docs offers.
If this is the case, that's really too bad, as I wanted to really try to cut the tie with my laptop and give a whole-hearted try at switching to the cloud.
Now, there's probably another cloud service (MS?) I could use that would have the oomph to run the type of spreadsheet I have, but that's annoying and not Chomebook simple.
... and ... this is just my personal budget. Not even close to they stuff I do at work.
