// - it specifies "/defaultlib:msvcrt.lib". this is troublesome because

// multiple heaps are active; errors result when allocated blocks are

|
// one workaround is to add "/nodefaultlib:msvcrt.lib" to the linker
|

// command line in debug configurations.

// cursor.cpp's efforts by resetting the mouse cursor after movement.
