Compose button problem

[Bill Tihen -- Information Technology]

Hello,

I seem to have a problem with the compose button that I am trying to track
down.  It seems that if I leave a compose window open for a long time (and/or
maybe resize the compose window), the compose button no longer works.  However,
reply does. 

If I restart Netscape, the compose button seems to work fine.  

Has anyone else seen this (or something similar).

IMP 2.2.2 (modified the session code so that shared memory works), Apache (from
horde website (1.3.12 I believe) and PHP3 from website.

Thanks,

Bill
