I had an odd problem today, seems not a problem before:

I am trying to upload a simple tab-delimited text file into galaxy, 

but it kept telling me:

empty
format: txt, database: hg19

Also, showed filesize as 0 bytes.

I tried Unix format, DOS format. It is a very small data, only 348 bytes.

4 rows, as attached. 

What is WRONG?

Thanks!
