Call to PerformClick method on Dotnet toolbar object stops execution.
I am calling "PerformClick" method on the DotNet tool bar object (class: WindowsForms10.Window.8.app.0.ea7f4a_r13_ad1), but it stops execution since this method doesn't return till I close the window ...
PerformClick is a native method of the control. Try using TestComplete's actions instead of it. For example, ClickItem or Click. Do you see the difference?
