Adobe Acrobat 8 vs. RS 2005 PDF Rendering

For the last two years I've had an application running in production which would generate and display its reports as PDF via RS 2005. It would take user parameters, render the report, and my application would take the PDF bytestream from RS and save it to a file on disk, then request Windows to open the file. This has worked very smoothly.

Recently there has been a push in my company to get Adobe Acrobat 8 deployed, and apparently the same PDFs which have been working all this time will cause Acrobat 8 to choke. By choke, I mean that Acrobat will load into memory but have some sort of problem with the PDFs, and never show up. The users, not realizing what is going on, will then ask for the same report again, causing two stalled instances of Acrobat to be opened now, etc.

Removing the new acrobat and replacing it with Acrobat 7 solves the problem. Long term, this is not a good solution however... Has anyone else had a similar experience? I've googled around and have come up empty.

I've seen Acrobat 8 act that when it cannot communicate properly with the Adobe updater. On a client that is experiencing that behavior, can you launch Acrobat 8 and manually ensure it is up-to-date?

Thanks.

|||Thanks Donovan,
I've passed this on to our tech support guys and will be doing a test later today myself on one of our spare workstations. I should be able to replicate the issue our users have seen - at which point I'll play with the Acrobat update options and determine whether they are the cause. I'll post a follow-up comment to this thread with the results.
