Calculator error recovery

Question

When running through the exercises in DIAdem 11.0 I have found that if I get the syntax wrong on a calculator function and the result line shows that "THere was an error in the calculation" that ANY subsequent calculation request that I type into the field continues to show Error in calculation.  Is there a way to reset the calculator other than shutting it down and restarting (closing the calculator and opening again?)
For example, I was using PNO("Roll 3", 100) - a command that works to find the closest first index to 100 in the channel data for Roll 3.  If I made a mistake and left off one of the quotes, press <calculate> and am told there was an error, correcting the error and pressing calculate again still indicates an error.
Thank you.

Ok - using the same method as before and doing a PNo("Channel", Condition) search and leaving off one of the quotes I was able to recreate the problem of not being able to run subsequent calculations.
When I made mistakes in a couple other simple assignments the calculator recovered on its own without closing and opening it (before doing recreating the PNo error).
After correcting the PNo syntax error and not being able to run a calculation again I did the channel creating that you asked about and it ran fine and created the channel.  I did a simple Ch("new")=Ch("old")+10 after getting the previous syntax error.
It seems that certain syntax mistakes are not self clearing?
Doing a simple assignment after getting the non Clearing PNo error did work.  It's only when I add back the missing quote and try to run the Calculate on the PNo.
