Screenshot 1

Every time Sibelius starts (version 6 as well as 6.2), some areas on the screen
are "frozen" making it virtually impossible to use the program, especially the
drop down menus (see the attached screenshot 1). The areas are still frozen,
when I switch to other programs or minimize Sibelius, so it affects the whole
system (see screenshot 2). They go away again, when Sibelius is closed.

Some of the areas keep showing the same image, others blend what is currently
behind them together with with what was previously there, leaving a trail eg.
when I move a window around. None of the areas prevent me from clicking
whatever they are obscuring, although obviously it is not possible to see, what
I'm clicking on.

The areas appear in exactly the same spot every time the program is run. Their
location is absolute and is unaffected by moving the main window or anything
else. However, they change position the first time the score is played
back/stopped.

The log shows four calls to LockWindowUpdate, two using the same handle, two
using nil. These calls may or may not be related to the frozen/locked areas on
the screen.
