open command box as timer.

I'm currently running a macro program that doesn't wait for any dos/java programs to complete. so my workaround is to open a command box, my macro waits for the command box to disappear.

When the command window goes to the background, sikuli can't see it for some reason that keeps the system paused.

please help.

for n in range(1):
# if exists("1469305284558.png"):
    reg = Region(609,140,894,766)
if reg.exists(Pattern("1469321512445.png").similar(0.50), 0) or reg.exists(Pattern("1470254195609.png").similar(0.50), 0) or reg.exists(Pattern("1470143332576.png").similar(0.50), 0):
        click(Pattern("1469305690339.png").similar(0.90).targetOffset(-70,-9))
 # wait(.5)
        type(Key.ENTER)
        type("v", KeyModifier.CTRL)
        type(Key.ENTER)
        type("s", KeyModifier.CTRL)
else:
        click(Pattern("1469222076906-1.png").targetOffset(-647,497))
        click(Pattern("1472489879950.png").similar(0.60).targetOffset(-60,-1))
        type("0", KeyModifier.CTRL)
        import os
        cmdPath = os.getenv("comspec")
        title = "Timer Runner"
        cmd = 'start "%s" %s'%(title, cmdPath)
        os.popen(cmd); wait(1)
        wait(5.0)
        type("exit" + Key.ENTER)
      # os.system("taskkill /im cmd.exe /f")
