happens both on MacBook and Mac Pro

It appears to me that Entourage treats F1 as an Undo key (equivalent to
cmd-Z). So if the last thing you did in Entourage was type something, F1 or
cmd-Z will delete it. Type cmd-Y to restore what you typed.

If this bevhaior really bothers you, you can change the behavior of F1 by
using the Keyboard & Mouse system preference. Under the Keyboard Shortcuts
tab, assign some equivalent you like better for the F1 key in Entourage.
