in reply to system calls problem

Is "blabla.exe" a program which runs for a long time? system returns when the program called from it exits. If you want to fire off a program without waiting for it, you'll have to look into calling fork and exec yourself (system does a fork and exec, but waits for the child process to finish).

Update: From the "blabla.exe" I infer that you're using a Windows system. A look at Win32::Process could also help if portability is not an issue.
