MW tends to be more intolerant of connection problems than any of my email programs, and piles on the arcane error messages that otherwise provide no useful information for either me or my mail services in diagnosing or fixing the problem.
Even if the error messages are suppressed, it does not resolve the problem of the apparent timing errors in accessing the emails. MW tends to have a higher fail rate with specific ISPs, but not others.
MW needs to have some advanced user controls to adjust whatever timing sequences for specific ISPs. MW would present a list of POPs from the listed email accounts, and allow the user to select any (or all) of the POPs needing adjustment or resetting to MW defaults.
