I have a project with tab strip for changing the main window. If I logout and change User then try to swap to a certain screen (with “file explorer” and “Adobe PDF Viewer”) the project shuts down completely. I only have two Users but this happens regardless of which way round I logout. The initial login opens the screen perfectly. If I try to close down the server I get an Adobe Reader error stating : “One or more PDF documents are open inside a web browser. If you exit Adobe Reader now, those documents will be closed etc” Any ideas? ![:scratch:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/76d1620bec252bfac07050c889ff5a91dc8a9c25.gif ":scratch:") Adobe Reader is version 8. I am at a loss how to monitor what is going on i.e. the “Console” does not give any indication - is there somewhere I should look to establish what is going on in the background? ---

I remember having some problem or other with the pdf viewer. I ended up using an IE window to dislplay the pdf. Might be worth a try. 😕 ---

Tried the IE window and unfortunately still does the same. ☹ ---

That version of windows, java, and Ignition are you using? I’ll see if we can replicate this issue here, although I can’t promise a solution (mixing ActiveX and Java isn’t a great technology) We’ve had the idea of licensing pure-java pdf rendering and browser components, but the cost is quite high. (for my future reference, this seems to be a [repost](http://www.inductiveautomation.com/forum/viewtopic.php?f=70&t=7274)) ---

Windows XP Pro Version 2002 service pack 3 (on a VM) Java version 6 Update 24 (build 1.6.0\_24-b07 Ignition 7.3.2 You mentioned on my duplicate post (dont know how I two??) not to use active X . I replaced this with the PDF viewer from the Reporting tab and clicking on the next page arrow or selecting a file causes the project to close. What are my options on this problem??? ---

Your best option is to pop-up the PDF, instead of displaying it embedded. You can do this with a scripting call such as [system.net.openURL()](http://www.inductiveautomation.com/support/usermanuals/ignition/index.html?system_net_openurl.htm). ---

What version of IE are you running? I recommend at least IE7. Something else niggling at the back of my brain about IE6, but can’t seem to remember what it was… ---

Just for the record it was IE6 so I upgraded to IE8 still same problem, going have to go down the system.net.openURL as advised. Just seems a shame to need to avoid certain features of Ignition. ![:scratch:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/76d1620bec252bfac07050c889ff5a91dc8a9c25.gif ":scratch:") ---

Yes, I know this is a bit of a bummer, but there’s a reason that the ActiveX module is free and not installed by default. It’s sort of offered “as-is”, since it uses a technology that we are unable to improve on. For what it’s worth, some customers are using it with success, but there is a large variety of factors that go into whether or not it’ll work well for any given use.
