This is a strange problem and everything I tried did not work.
I have a very large single Manipulate cell (it is a demonstration stylesheet notebook, hence this cell have to be one), and I simply wanted to copy the content of this cell and paste it into another text file.
It seems that, for some reason, Mathematica has a limit somewhere, since I am sure the windows 7 clipboard can handle this size itself.
When I select the cell, and then do CTRL-c, and paste into a plain text file in my editor, the output that shows up is only about 850 lines (this is much less than the original cell, which is I think few thousands lines long). I tried two different editors with the same result. It always gets cut off at the same place.
The copy has to be done as
input text and not as
plain text. The copy as
plain text is able to copy the whole cell, but the formatting is all messed up and not possible to read.
I need to copy it as
input text, which what happens when selecting the cell and doing CTRL-C, then CTRL-V (on windows)
I can save the whole notebook as .txt file, but again, the formatting is all lost, and it seems to save it using the
plain text mode.
I can offocurse break the cell into many smaller cells, and then copy one by one with the mouse, but this is very tedious way to do it and I think there should be a way to handle this directly.
Here is the notebook and I hope someone can find a way. I have many such notebooks with large cells to do.
I am using version 9.01 on windows 7 64 bit.
