Good morning, i have this strange issue, in a company with 30 pcs,win xp sp3,office 2007 we have installed eset endpoint internet security. in some pcs occurs the following:when ever the user composes a new email in outlook and tries to switch the input language either by alt-shift or by the language button outlook hangs and is not responding.When i disable eset protection outlook works without a problem. any idea? thank you.
