SebuS, I tried opening your VI in LabVIEW 6.1, but it gave me the error msg that the VI is actually LabVIEW version 7.0. Also, I ran your sequence in TS2 with this LabVIEW 7 VI, and it works just fine to click the OK button. I'm sorry I've not been able to replicate this problem for you.
Do you have the TestStand 2.0.1f1 patch? You can open the TestStand Sequence Editor and click Help >> About to check the TestStand engine version. This was the last release for TestStand 2.x versions, which you can download from this site: <a href="ftp://ftp.ni.com/support/teststand/updates/2.0.1/ts2.0.1f1_patch.zip";>TestStand 2.0.1f1 patch</a> David Mc.
