I'm using SDL 1.2.9 with Visual C++ 7.0 on Windows 2000.
Here's the setup: my game starts in a window, with
SDL_WM_GrabInput(SDL_GRAB_ON) to constrain the cursor to the game window. The
mouse cursor is outside of the window when the game launches, and when the
window appears the cursor is grabbed and placed at the top left corner of the
inside of the game window. At this point, if I click the mouse without moving
it, the SDL_MOUSEBUTTONDOWN event's mouse coordinates are (65535,65535).

Subject: Possible SDL bug
Greetings
I believe Ive come across a bug in your SDL product (1.2.9), in the CD-ROM
control portion of the library.
When calling the SDL_CDPlay() function to play the last track of a CD using the
offset and length from an SDL_CD structure generated by SDL_CDOpen(), I get the
following error from a call to SDL_Error():
mciSendCommand() error: The specified parameter is out of range for the
specified command.
The code returning the error is:
SDL_CDPlay(g_playingDriveSDLCD,
g_playingDriveSDLCD->track[trackNumberInt].offset,
g_playingDriveSDLCD->track[trackNumberInt].length)
Subtracting one from the length of the provided length seems to repair the
problem:
SDL_CDPlay(g_playingDriveSDLCD,
g_playingDriveSDLCD->track[trackNumberInt].offset,
(g_playingDriveSDLCD->track[trackNumberInt].length) - 1)
Ive replicated this problem on Windows 98 SE (several months since last
patch), fully-patched Window ME, seldom-patched Windows XP SP1, and
fully-patched Windows XP SP2.
While investigating the issue, I came across a line in your librarys win32
source code in file \src\cdrom\win32\SDL_syscdrom.c (source code zip archive
from your download page), function: SDL_SYS_CDGetTOC(), line 226 where you add
1 to the value for length to fix MCI last track length bug. This may be the
source of the issue (because subtracting 1 from the length seems to resolve the
issue). Microsoft may have patched the referenced bug since you wrote that
line.

Subject: [SDL] Windows MessageBox() strangeness fixes
Hello all,
I *think* this should fix the issues that people were seeing with
MessageBox() not working and therefore assert() on mingw/msvc. Forgive
me if i've screwed up making the diff file - I'm a total newb when it
comes to things like CVS and diff.
It modifies a few files as I saw that FlushMessageQueue() was in both
the windx5 and windib driver, so I moved this into wincommon. It was
also in the gapi driver, so I changed that too. The function is now
WIN_FlushMessageQueue() in src/video/wincommon/SDL_syswm.c

fixed bugs 159 and 160:
+ added threaded timers support
! fixed restoring sdl window focus (AV in windows message handler)
! disabled forgotten cdrom and joystick in config file.
* disabled minimizing sdl window while loosing focus.
PocketPC does not have a task bar, so it is an inconvenient and unusual
behaviour for PPC users.
+ added WIN_Paint handler for GAPI
! fixed loosing focus while using GAPI videi driver
+ added TestTimer project
* removed unnecessary macros (ENABLE_WINDIB ...) from projects
