Has anyone experienced this scenario and figured out a solution…
A user opens up access point and IE hangs and doesn't refresh with any documents… Than at times if it opens, and they click on a document, if they move to another app while it opens up the qvw, it will just sit there and not load and be a blank white IE page?
They have to ctrl, alt dele and kill IE and restart it again. If they click on the qvw in access point and waits for it to open without moving to another app, eg. Excel, or outlook, it will open fine..
Try this: IE --> Tools --> Manage Add-Ons. Find Adobe PDF Link Helper and disable it. Restart IE and see if it still crashes. Also, of course you should only use IE 32-bit since 64-bit is not supported.
Run QvServerPerformance.qvw against your server logs and look for tunneling activity. It's possible that your server is being overloaded because traffic can't get through port 4747 so it has to tunnel over HTTP. If this problem is happening from all PCs then it's almost definitely a server/network issue and QvServerPerformance should give you some hints even if it turns out not to be a tunneling problem.
Also, have you tried opening the AP in FireFox? Any luck with that?
I'm not sure what you mean by "user key." If you mean that the CAL is corrupt, that's pretty easy to fix. Just delete the PGO files in your root AP folder and in C:\ProgramData\QlikTech\Qvs. They will get automatically recreated without any corruption. You may need to have services stopped before you delete the files.
I would still recommend giving QvServerPerformance a shot and seeing if anything jumps out at you.
