What does this message mean and how to get rid of it?

[apattin]

When I close textpad I often get this message:

OK To create "C:RestartByRestartManager<bunch of number s and letters>?

What does this mean and can I get rid of it?

Thanks!

Does this message appear at random or when a specific file is opened. Any other information about what you were doing just prior to the message appearing might be helpful. Thanks.

This was also happening to me, but only after crashes where I had saved
a file encoded as PC as UTF-8 BOM; noticed the error, saved again as
UNIX. Solved (apparently, hasn't happened again) by copying the text and
creating a new properly set up from the start file.

Textpad has stopped working with an unrecoverable problem. click that
off and this file pops up. I figured some sort of crash log.

EDIT:
This looks to me like it might be related to this problem:

I just scanned a document and saved it as .txt (Abby Fine Reader). I then edited this document adding in diacriticals. When I attempted to append (by copy and paste) this document to an existing UNIX UTF-8 BOM file, I got the:
"Some characters in this document ... error message". I double checked.
I had to copy and paste the whole file to a new document in order to save it.

This, with complications, is what I had done previously and I suspect had I persisted in trying to save the original document, the above error message would have been generated.

The problem seems to be that even when appending a PC encoded file to a UNIX encoded file, the line endings, not changing, causes a problem.

I had thought that saving the file as UNIX would have changed all the line endings.

I do not recall this happening previously and I have done may similar operations.
