Full-screen application switching problem

SDL Development
1

I have a full-screen SDL application running on Windows 95, compiled with
MSVC++ 6 and linked with SDL 1.1.3. I do not want a mouse cursor within my
application, so I call SDL_ShowCursor(0). The problem is that when I switch
to another application (either by pressing alt-tab or by spawning the new
application), the mouse cursor does not reappear. Is this a bug, or correct
behavior? In either case, how do I fix it?–

Update: There are two different problems here: pressing alt-tab leaves the
mouse temporarily invisible. Spawning a new process (through ShellExecute)
leaves a visible mouse cursor on the screen, BUT I CANNOT MOVE THE CURSOR
BY MOVING MY MOUSE. I tried catching the SDL_ACTIVEEVENT event and calling
SDL_ShowCursor(1) upon losing mouse focus and SDL_ShowCursor(0) upon
regaining it - no effect.–

That’s pretty wierd. :slight_smile:

How about when you gain and lose application focus? Keyboard focus?

I wasn’t able to reproduce this here. Are you grabbing the input as well?
Can you send a simple test case to @slouken? If possible send it
today, since I’m working on Win32 SDL today.

Thanks!
