   Parameter AValue is an optional Patience value.
   If AValue > 0, Patience is set to this value;
+  else if Patience=FULL_PATIENCE, no changes;
   else if RunMode = rmSingle, Patience is set to 4;
   otherwise Patience is incremented by 2 (up to maximum of 4).
+
+  Note: When MorePatience was introduced in May 2024, a bug (Issue #370) was
+  introduced causing the DxStation to not send an 'R' after the user corrected
+  a callsign. The case involved the user sending a corrected callsign using
+  the Enter key while leaving the exchange fields blank (user sends
+  '<his incorrect call> ?'. In this case, the DxOperator.MsgReceived function
+  would call MorePatience for the '?' and the Patience value was set to 4.
+  This caused DxOperator.GetReply() to send the wrong response:
+      DxOperator.GetReply(osNeedEnd, Patience=5) --> 'R <HisCall>'
+      DxOperator.GetReply(osNeedEnd, Patience=4) --> '<HisCall>'
+  To fix this problem, MorePatience will maintain an existing Patience value
+  of 5 (FULL_PATIENCE) and not set it to 4. Resolved in October 2024.
