What version are you running? Did you refresh the QMC web page manually or do you have checked the autorefresh? How long since you last restarted your QlikView services? Does that happen with only one document or all of them? Is you antivirus software skipping .PGO, .Shared and .Meta files?
I'd first try to go to the Services.msc console and restarting QlikView Server service and see whether or not that does for the time being.
Thanks Miguel for the promopt reply! I am using version 10. I have manually refreshed QEMC a few times. You said QMC, i manually refresh User Documents part, still the same.
I just restarted the server, it fixed the problem. It has come to my attention lately that qvbs.exe has been steadily increasing even no one is accessing web. Any idea why?
