Script works, setting breakpoint complains about unable to find the object

Hi,

It is my understanding that Locals pane implements a kind of 'lazy evaluation' in order to speed things up.

I.e., when test script stops on a breakpoint with Locals pane visible, TestComplete starts evaluation of all local variables to get their values. If a variable references some UI element, TestComplete tries to get a reference to it and, if the object does not exist, then TestComplete tries to re-evaluate it (via search through the UI objects hierarchy, which is time consuming, but this is your case).

I would recommend to not keep Locals pane visible unless you need it and hide it (switch to some other pane) before resuming script execution.
