Abstract:
|
||
|
|
|
||
|
|
This is a workaround for a problem created by SafeDisc 2.0. The application
|
||
|
|
uses the WM_ACTIVATEAPP message to determine if it has focus or not. The
|
||
|
|
Safedisc wrapper prevents this message from hitting their main window on
|
||
|
|
NT, because it goes to the SafeDisc window before everything has been
|
||
|
|
unwrapped. So the app never thinks it has focus.
|
||
|
|
|
||
|
|
The fix is to send an activate message after the window has been created.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
