Subject: [SDL] Re: Modifier keys pressed during initialization stick
I wrote a simple test program which initializes SDL, prints the SDL
version number, then prints any keydown and keyup events with their
modifiers. (Source code below). Compilation was done using Visual
Studio 6, release mode.
My test sequence was:
Start a command prompt. Type the name of the test program.
shift down
enter down (program starts)
Wait for window to appear
enter up
shift up
spacebar down
spacebar up
Under Windows 98, the output was correct:
SDL 1.2.8
left shift down
shift-return down
shift-return up
left shift up
space down
space up
Under Windows 2000 and under Windows XP, the output was:
SDL 1.2.8
shift-space down
shift-space up
Since shift was not held at the time space was pressed, this is
incorrect. Similar results were observed with launching in different
ways (including double-clicking in Windows Explorer), so it does not
depend on the launching terminal.
