Can't find an object after record the test

Hello guys!

I have a test case, which I can't fix. It looks like a bug appears in the TestComplete, or maybe som eanother things happens which I don't know.

So, what we have. I have record a test case and after executing, I get an error, that unexpecter window appears. But there is not unexpecting window. Maybe you point me, what I'm doing wrong.

The part of the test case doing few actions:

1. Click on the object (this object is selected).

2. Click on 'Property' button. (A new property window opens).

3. Click in this window on the 'Ok' button. (Here is a probem).

On the third step, the TestComplete said me that unexpecting window appears, and test fails.

To fix the problem, I have found the line of code where it happens. Make a double click on this line of code. An 'On-Screen Object' window opens, where I push the 'Highlight' button to see 'OK' button in my aplication, but error window opens with information 'Cannot highlight this object on screen'. Then I push the aim button and drag it on the 'OK' button in my application. After that I push the 'highlight' button again, and this button marks with red square, which means that the TestComplete can see this button. After that I click the 'Finish' button to save the changes.

 After that I do right-click on the line of code, which should make a click on the 'OK' button, the menu opens where I select the 'highlight on screen' menu, but again an error message opens with information that this object cannot be highlighted.

 What here going wrong?
