#5 Menu key on Nokia clears stack element

[Anonymous]

As said, if when using midp-calc (latest Nokia version) I press Menu key on my Nokia N78, for example for opening another app or going in the menu, when I come back to Calc, the more recent element of the stack is cleared... If the stack is (from top to bottom) 1-2-3-4 , coming back I find 1-2-3...
Doing it N times clears the N more recent elements in the stack.
