Hi Cristian

I'm now on svn1126445.  Contrary to what you suggested, that's a big 
improvement in speed!  Editing the cleared status happens much as in v1.x.  So 
far as entering schedules at startup is concerned, that, too is much faster, 
although the window bounce is still as frantic.  If anything, it might, on a 
rough timing test (me counting as fast as I can), be marginally faster than 
v1.x!  Entering/accepting an edited transaction cause just one slow bounce!   
That's all I've looked at so far, but I suspect new users would not think 
there's a problem, apart from the bounce, that is.

Well done, that man.
