Comment (by stippi):

 Hi Stefano, thanks for picking this up. I investigated this one a bit the
 other day and it should have to do with Undo and the codepath for it. If
 you use TextView::Insert() directly, no Undo event is generated and this
 is the cause for the bug. I don't know if the original DeskCalc worked the
 same way as the current one, you probably need to make a test to find out
 if R5 TextView::Insert() generates an Undo step... if not, the problem is
 in DeskCalc, since BS just invokes Undo().
