Thanks for your response. I'm still running into this with 1.5.21. The
background process has to be ran from a script, as in the example I provided
above. If you kick the script from the command line, this problem does not
occur. If you run the example above with ./file1.sh, you should see the 
problem. I didn't run into this with DLL version 1.5.18. Here is the bash 
and DLL versions of both:

I also tried Bash 3.00.16(11) with DLL version 1.5.21 and still had a
problem. I see this on several machines so it's not isolated to one.

Thanks for your help and any info you can provide,
->Steve
