I have noticed that since upgrading to Win7 on my Dell Studio 17, I am not able to open most adobe attachments. It appears to be opening, but rather I get a nice big gray box, with a little gray box in the middle of it, with no message at all. Not even an error message. I have tried re-booting, and sometimes that will clear up the problem just that once.
Any ideas on how to proceed? I am not finding much help on the web site, here. I'm not a big computer/software person, but can find my way around a bit. The computer came with Acrobat 9.0, which I have not updated.
