+Applying patches by hand
+========================
+
+The full altered functions are given below in case you have
+to apply them by hand.

+
+A second test has been added to this line:
+
+ if(hittest == HTCLIENT || hwnd == GetCapture()) {
+
+in MwTranslateMouseMessage below. This corrects a mouse message
+bug.
+
+/*
+ * Translate and deliver hardware mouse message to proper window.
+ */
+void
+MwTranslateMouseMessage(HWND hwnd,UINT msg,int hittest)
+{
+ POINT pt;
+ DWORD tick;
+ static UINT lastmsg = 0;
+ static HWND lasthwnd;
+ static DWORD lasttick;
+ static int lastx, lasty;
+
+ /* determine double click eligibility*/
+ if(msg == WM_LBUTTONDOWN || msg == WM_RBUTTONDOWN) {
+ tick = GetTickCount();

+
+Part of PeekMessage has been factored out into PeekMessageHelper,
+and used in PeekMessage and GetMessage. The three relevant functions
+are:
+
+/*
+ * A helper function for sharing code between PeekMessage and GetMessage
+ */
+
+BOOL WINAPI
+PeekMessageHelper(LPMSG lpMsg, HWND hwnd, UINT uMsgFilterMin, UINT uMsgFilterMax,
+ UINT wRemoveMsg, BOOL returnIfEmptyQueue)
+{
+ HWND wp;
+ PMSG pNxtMsg;
+
+ /* check if no messages in queue*/
+ if(mwMsgHead.head == NULL) {
+ /* Added by JACS so it doesn't reach MwSelect */
+ if (returnIfEmptyQueue)
+ return FALSE;
+
+#if PAINTONCE
+ /* check all windows for pending paint messages*/
+ for(wp=listwp; wp; wp=wp->next) {
+ if(!(wp->style & WS_CHILD)) {
+ if(chkPaintMsg(wp, lpMsg))
+ return TRUE;
+ }
+ }
+ for(wp=listwp; wp; wp=wp->next) {
+ if(wp->style & WS_CHILD) {
+ if(chkPaintMsg(wp, lpMsg))
+ return TRUE;
+ }
+ }
+#endif
+ MwSelect();
+ }
+
+ if(mwMsgHead.head == NULL)
+ return FALSE;
+
+ pNxtMsg = (PMSG)mwMsgHead.head;
+ if(wRemoveMsg & PM_REMOVE)
+ GdListRemove(&mwMsgHead, &pNxtMsg->link);
+ *lpMsg = *pNxtMsg;
+ if(wRemoveMsg & PM_REMOVE)
+ GdItemFree(pNxtMsg);
+ return TRUE;

+
