QC 9.2 Test Lab folder content keeps disappearing
I have a problem with Quality Centre 9.2. The content of folders in the 'Test Lab' keep disappearing. The folder structure/hierarchy remains but the actual tests are not displayed. This seems unique to my login/machine. If I select a link to a test from a defect I get a message saying 'The test set does not exist or you do not have permission to view the test set'. I have to log out/in several times or wait a while before they re-appear, its a hit or miss whether they appear. I have attached a screen print of the 'Test lab' and error message. Has anyone else seen this or can suggest a solution?
I also get lots of random error messages which I have attached a copy of.
Many thanks in advance
