Question about lvl 12, Pepper Panic Saga...

The above level is a puzzle level (progress by creating pepper combinations).  The fourth one asks for 3 blue peppers.  I can make the blue pepper combo (once as a T, a few times with other combinations in tandem, once as a single line of 3) but after it shows the bracket (acknowledging the combo happened) the computer freezes.  The group of blue items does not disappear and in-game functions cease to work.  I can only quit and start over.
