Judging by what "Nil" wrote in his reply, that "TClockEx" has a
"Pop-up calendar", I am thinking the most obvious difference
between it and "TClock.exe" is probably going to be that it is
much lighter [smaller] and therefore tend to be more reliable, not
least on display quality (video memory).

TClockEx is perfectly stable. It has never been any kind of problem for
me.
