It appears that the GetAncestor() function and GA\_ROOT are defined in  
WinUser.h. However, they are only defined if “#if(WINVER \>= 0x0500)”

Since the default for Windows.h is to define WINVER to 0x0400 this means these  
functions are not available. Can someone who has check-in authority (Sam?)  
please #ifdef the changes to dx5events.c that Trevor Scroggins made to version  
1.22 of that file.

Thanks,
