This is where the problem is coming from. On my system I get:
Got ideal size: a Size (181, 54)
width: 181
height: 54
Your height of the button look approximately 1,000 times the height of the
screen.
The screen blanking and the CPU going are probably the result of the
operating system trying resize the bitmap for the button to a thousand
times the height of the screen. Or comes from the operating system trying
to paint that huge of a bitmap.
The rest of the stuff, distorted dialog, etc., is coming from the OS trying
to draw the scaled bitmap. At 32-bit color, the huge bitmap would need a
lot of memory.
This gives me something to look at. The size returned comes directly from
the operating system though, so I'm not sure what the problem is.

Some process has either oodialog.pdf, oodguide.pdf, or oodialog.dll open so
that it can not be deleted. It could be one of those files is selected in
Windows Explorer. Or, maybe you have the documentation set to open on
start up, or ...
