This has nothing to do with Visual Applets issues.
I have a question about APC callback of SDK.
Q1. When FG_APC_HIGH_PRIORITY is set, does it always have priority over user-created threads(Multi threads)?
The user thread does not set priority.
Q2. A callback function is registered and used only once.
In an environment where users repeatedly start and stop Grab, will the APC priority still be HIGH_PRIORITY maintained?
