Jon,
You are correct. We have V6.3.3 and AdobeX. We'll upgrade to the newest reader version. Thanks!

Serene,
The seemingly random crashing is unusual. All I can think of now is to be on the lookout for any patterns (e.g. computers, time of day, etc) and to contact support if you haven't already done so.
Also, I have to issue a correction to something I said earlier in the thread about AC and Imported-Items crashing. I said that the Imported Items crashing happened upon the maximization/minimization of the patient's chart if a pdf document had been selected for viewing. I remember it being this way, but I tested it out again, and apparently it
only crashes whenever I
minimize it and then un-minimize it. Maximization works fine.
