This just came across the patchmanagement.org list and I thought it significant enough to re-post here.
Updating Adobe Acrobat to 9.4.2 (the recently released security patch) can break printing of PDFs. Does not affect Reader. Confirmed by Adobe. Acrobat 10 (X) is unaffected. This aspect is not confirmed by Adobe as yet. Adobe suggests it's limited to certainly printer models, but other people suggest it may be something else. http://forums.adobe.com/thread/789250 Thanks to Lars Nelson for the tip. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
