3DFrogFrenzy.cpp

|
Abstract:
|
||
|
|
|
||
|
|
Workaround for a USER bug (or by design behaviour) where if you call
|
||
|
|
SetCursor(NULL) and the cursor is over somebody elses window, the
|
||
|
|
cursor stays visible.
|
||
|
|
|
||
|
|
We don't normally see this because most apps that want the cursor to
|
||
|
|
be invisible are full-screen: so the cursor is always over their window.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app-specific shim.
