Mozilla Suite - Email icon in Systray -- NOT!

[Peter Creasey]

For a long time I have used Mozilla Suite to handle my email on the Win XP Pro system. Upon the arrival of new email, Mozilla Suite always gave a tonal alert and placed an envelope icon in the Systray in the lower right bar.

Recently, with no updates to Mozilla Suite, the envelope icon is frequently NOT being placed in the Systray in the lower right bar. All other indications/alerts of the arrival of the email still work fine. I have not been able to determine any particular circumstances when the envelope icon alert fails to work.

Any ideas as to why suddenly the envelope icon is often not being placed in the Systray in the lower right bar?
