[Bug 13683] Ultima IX: Mouse pointer missing when reading books, under inventory

http://bugs.winehq.org/show_bug.cgi?id=13683

--- Comment #22 from Christopher Thielen  ---
I haven't tried +cursor,+icon,+resource yet but will now.

I've been trying to figure out through what mechanism the game draws a cursor -
I placed some TRACE statements in the d3d9_device "ShowCursor" code and saw no
change in the output. I'm now trying to identify exactly what code paths cause
the X cursor to appear/disappear with the hopes that I can figure out _how_ the
u9.exe binary is polling for the cursor position and, hopefully, if it's
drawing the cursor by itself (e.g. not with DX's ShowCursor), determine the
particular resource that is failing to draw.

I'll post my findings here and follow-up questions on wine-devel.
