I've been working on a fairly complicated test. This morning when I open it up, it takes a long time to open up. When it comes up, half the actions are missing. I don't save but folder/file dates have changed in the test folder. I open it up again and all but the first action are gone. In the test folder, all the action folders are present. But several files have new modified date/times: [testname].usr, lock.lck, parameters,mtr, test.tsp, and all the action folders (though none of the files underneath are modified). I'm using qtp 10. I've been working with QTP for a year and haven't seen this. I've been using 10 for a couple of months with no problems. Any ideas what might be happening?
