Question:
I set my Active Object priority to EPriorityLow but it seems to run at EPriorityHigh

Answer:
Be very careful when you create an active object with priority EPriorityLow or EPriorityHigh. These constants have two different definitions depending on whether you are in the scope of CActive or not.
E32STD.H defines EPriorityLow as 150 and EPriorityHigh as 450.

CActive defines EPriorityLow as -20 and EPriorityHigh as 20.

So if you are outside CActive scope, make sure you use the CActive:: scope qualifier for active object priorities. If you don't your active object will be higher priority than you might expect.
