When I saved a file in a WPF application, Test Studio added step „Handle “SaveFile”dialog” with Filetype, DialogTitle and etc. (It’s OK) But when TestStudio start executing this test, It stopped on the step "handle Save dialog" with error „Timed out waiting '10000' msec. for any dialog to be handled '1'”, but this dialog is shown and active in application, Test studio didn't identify it. After some tests I found that if I manual change a “Handle SaveFile” step with “Handle OpenFile” step and change Dialogtitle and HandleButton to „Save As” and „Save” the test will be executing correctly. After these changes, when test executing, Test Studio identify „Save window” as „OpenFile” dialog, and correctly save a file and continue to next step.
