I noticed a bit of odd behavior with the Dropbox icon in IceWM.

If I start up antiX with IceWM, and leave it in IceWM, then the Dropbox icon is there as it should be.

However, if I switch from another WM to IceWM, then the Dropbox icon isn't there.
I've tried switching WMs, and the task bar in JWM and Fluxbox both show the Dropbox icon. But it disappears in IceWM.
It's still working, though. But the icon doesn't display in the task bar in IceWM.

Am I right in assuming it's really nothing to worry about?
Just a wee aesthetics issue that can be fixed in the fullness of time?

Thanks.
