Error: "cannot create file ..."

[Rocky]

Dear users,

The SDA software is really cool.

Here is my questions:
1) When I import txt file using TIW, the last step is always there
(100%). After I click "Finished", it always shows "cannot create
file ...". But when I opened "Data tab", the txt has already been
added and can be shown in the time plotter. Is it ok or not?

2) I can get large fond size for Y-axix in the Time series plotter,
can anyone tell me how to get large size for the X-axis?

3) How can I put simualted flow and observed flow together in one Time
series plotter via this software?

Your help is appreciated greatly.
