Just so it's not lost, I'm copying this bug from the forum
(the post at http://vogons.zetafleet.com/viewtopic.php?t=35350 contains pictures and a proposed fix).
Set-up: I'm using DosBox 0.74 on Windows 7 74-bit.
I have two batch files.
@echo qqq start!
@echo qqq finish!
If I run QQQ.BAT directly from DosBox, I get all three lines printed.
But if I try to run this batch file from under any shells similar to the Norton Commander (Dos Navigator, Volkov Commander, Frunze Commander), "CALL WWW.BAT" doesn't seem to return control from WWW.BAT back to QQQ.BAT and only "start!" and "www!" get printed.
If I exit whatever commander I'm running and run QQQ.BAT again, all is back to normal, all three lines are printed.
The proposed (in the forum) fix is attached.
