Sys.Waitprocess is causing my process to end

I cannot say for sure what causes the difference. You can find the information about the differences between TestComplete 6.53 and TestComplete in the following help topics and those related: Version History: http://support.smartbear.com/support/viewarticle/12598/ What's New in TestComplete 8: http://support.smartbear.com/support/viewarticle/12597/ Also, we could try to determine the cause of the crash if you collected some additional information in the following way: 1. Download AQtime Standard, which is our free profiling tool, from our web site: http://downloads.automatedqa.com/AQtimeStdx86.exe 2. Install the tool. 3. Start AQtime with the -NotOpenApp command-line argument. For example, you can use the following command line: "c:\Program Files\SmartBear\AQtime 7\Bin\AQtime.exe" -NotOpenApp 4. Select the 'File | Open...' main menu item. 5. In the Open File dialog, select the tested applicaiton's executable file and click Open. 6. Take a look at the AQtime toolbar - there is a combo box. Open it and select the "Tracing | Exception Trace Profiler" item. 7. Select the "Options | Options..." main menu command - the Options dialog will appear. 8. Enable the "Profiling Time | Event View | Debug Events | Generate dump on exception" option and specify a dump folder. 9. Set the "Profiling Time | Event View | General | Exceptions | Depth shown" setting to 100 and click OK. 10. Click the Run toolbar button (the green arrow) or press F5 to start the profiling. 11. AQtime will start TestComplete and generate dump files for all exceptions that will occur in the application until it is closed. 12. Reproduce the problem using TestComplete. 13. After the problem occurs, right-click somewhere within the Event View panel (it is opened by default at the bottom of AQtime's window) and select the 'Save All...' item. 14. Save the panel's contents to an HTML file and send me the file along with all of the generated dump files.
