In the code below, two of the right brackets , a square ']' bracket on
line 15 (2nd one from right) , and a curly one on line 34 (only bracket
on line)
are hilighted in red indicating no match...
but putting your cursor over them shows its matching pair
(and the program works fine as it is...so am pretty sure they are not
unbalanced...)
Any ideas why the red hilighting?
TIA..
