Output - Wrong order of returned lines using 'Run Program' to launch Perl scripts

[VBPbetaTest]

But when I launch directly from DOS prompt "ccperl.exe myscript.prl", the result on the screen is ok.

Print ----------------------------------
Print Name of my program
Print Date – Time
Print Parameters
Print ----------------------------------
System('cleartool.exe DoMySomethingInClearCase')
Print End of the treatment – Time

Could the stdout captured by 'Run Program' action be different from the one of the DOS prompt?

Thanks for your help
