Abstract:
|
||
|
|
|
||
|
|
This shim hooks LoadImageA to intercept the loading of two
|
||
|
|
cursors and returns copies of the system cursors instead of
|
||
|
|
the ones RiskII was trying to get. RiskII's cursors were
|
||
|
|
being rendered by software and it caused them to flicker since
|
||
|
|
RiskII locks the primary surface. The system cursors are
|
||
|
|
hardware cursors and don't flicker.
