[Dev] flicker in the calendar

[Alec Flett]

No, not Flickr... flicker!

The calendar has started flickering like crazy, especially when dragging 
or resizing. This is due to a wx bug that David S uncovered earlier this 
week (one of the recent wx updates disabled his original code which made 
the flicker stop..doh!) - anyway, he tells me has reenabled his old 
stop-the-flicker code in our tree and that the fix should be in soon 
(and that will also fix the transparent splash screen issue, if anyone 
is also seeing that) - I'm assuming in the next tarball.
