One tricky way to get the same info, though, is to listen to the Windows message queue using PeekMessage/GetMessage, and retrieve the X,Y coordinates from ANY received message in the pt field. Checking this box makes DxWnd fix the X,Y coordinates in this uncommon situation as well (see the game Uprising).</span></p>

This option makes DxWnd automatically process all these messages that an application might not correctly handle. It should be turned on if operations like window resizing or movement cause crashes or other problems.</span></p>

The operating system considers any application that does not do this within a defined timeout period (about 5 seconds) to be malfunctioning, and kills the process (although it keeps displaying the window's contents). Programs developed before Windows 7 didn't take this constraint into account and may easily fail to get messages during processes such as unskippable cutscenes or long calculations. This option periodically empties the system queue, ensuring that the program won't be killed. However, there is a small chance that some events (like mouse clicks) could get lost occasionally and will need to be repeated.</span></p>
