I have an application that I have been developing & an re-occurring error has me quite confused.

In the code, I have a statement that goes something like:

Generate a new problem.

If (ArithmeticID = 1) then

    If ForceAddition = true then

         Call GenAddition()

   Else 

         'Restart this loop

   End If

ElseIf (ArithmeticID = 2) then

   If ForceSubtraction = true then

         Call GenSubtraction()

   Else 

         'Restart this loop

   End If

ElseIf (ArithmeticID = 3) then

   If ForceMultiplication = true then

         Call GenMultiplication()

   Else 

         'Restart this loop

   End If

EndIf

That statement is inclosed within a try catch statement with the catch reading

" Catch ex as StackOverFlowException

     <blah blah code here>

  End Try

However, there is a crash caused by an StackOverflowException in this very statement & the Try,Catch does not seem to work.
