Thanks for the report, Vardoger ...
I'm pretty confident the problem has something to do with downloading the smilies from the forum server (which is in North America).
The odd part is why there seems to be a consistent set of smiley calls that are timing out during the download process. My experiments indicate the number and identities of the smilies that time out (and never arrive) can change from call to call - sometimes including additional items above and beyond the ones noted above.
The outages don't correlate with smiley name, size or date of accretion to the available set.
I'll have to refer this to our tech cadre.
