32 * MS uses a critical section at a few locations. However, I fail to
33 * see the reason for this. Their comdlg32.dll has a few race conditions
34 * but _not_ at those places that are protected with the mutex (there are
35 * globals that seem to hold info for the wndproc).
36 *
37 * FindText[AW]/ReplaceText[AW]
38 * The find/replace calls are passed a structure that is _not_ used
39 * internally. There is a local copy that holds the running info to
40 * be able to combine xxxA and xxxW calls. The passed pointer is
41 * returned upon sendmessage. Apps wont break this way when they rely
42 * on the original pointer. This will work as long as the sizes of
43 * FINDREPLACEA == FINDREPLACEW. The local copy will also prevent
44 * the app to see the wine-specific extra flags to distinguish between
45 * A/W and Find/Replace.
