Chrome version: 20.0.1132.57 m
ZCS 7.2.0 updated from 7.1.1 which was updated previously from ZCS 6

I did an update to the latest release to see if it would solve the issue but it did not.

The problem does NOT occur in Internet Explorer 8.0

Is it my install that is wrong?

I have several computers what show the same behavior...

Also: if I reload the page in Chrome, the display is ok until the page completes it's reload, then the icons disappear... magically

Maybe related: when I attache a picture to an email and activate the checkbox to "Show images in message body" and then read those email in the web client, the images will show for approximately 10-30 seconds and then suddenly disappear.

Maybe I have a Gremlin on my server that is playing around with my brain... ;-)
