I`ve got Windows server 2008 R2 with GW2012 client installed. The problem is that GW client freezes all the time when users tries to close attachement file. For example user receives e-mail with pdf document, he opens it (right click on attachment file, open) with Adobe Reader and then when he is closes Adobe Reader application GW client hangs. It doesn`t matter of attachement file type (the same situation is with xls, doc files etc.) The problem exists on every user account, including administrator`s one. How to fix this?
