I'm new to this product and these forums so please bare with me :)  I have been consistently experiencing OutOfMemoryException issues when I run my script...I don't believe I have done anything out of the ordinary so I'm a little frustrated as this is my trial run and it's not going so well.

Executing Script from TestStudio standalone
roughly 720 rows are binded to MainTest
While Script is running, ArtOfTest.Runner.exe is exceeding 1,200,000 K in Memory...
Script is ran against IE 10
I have also used the 'Reuse App Window' property (changed from 0 to 50 and even tried 10 and still does not help memory leak)

Build version is '2013.1.911.0'

'11/25/2013 12:05:19 PM' - Using .Net Runtime version: '4.0.30319.1008' for test execution. Build version is '2013.1.911.0'.

'11/25/2013 12:21:29 PM' - Test completed!

Here is how the script is structured...
Main Test (binded to Database) 
-> calls subTest
->navigates to Url
->check if an element exists
->assert true/false

// Execute test 'Verification'
           }catch(NullReferenceException e){
           }catch(TimeoutException t){
           Log.WriteLine("Timeout exception....");

[CodedStep(@"Navigate to vanity url]")]
       public void SubTest_CodedStep()
           // Navigate to : 'http://- DataDriven: [$(Vanity)].com/' - DataDriven: [$(test)]
           String vanity = ((string)(System.Convert.ChangeType(Data["Vanity"], typeof(string))));
           String fullUrl = "http://" + vanity + "";
           Log.WriteLine("NAVIGATING TO: " + fullUrl);
           ActiveBrowser.NavigateTo(fullUrl, false);
       [CodedStep(@"Verify element 'DealerLogoPanelDiv' 'is' visible.")]
       public void Verification_CodedStep()
           // Verify element 'DealerLogoPanelDiv' 'is' visible.
           Log.WriteLine("starting test findDealerLogo");
           HtmlFindExpression expr = new HtmlFindExpression("id=~DealerLogoPanel");
           ActiveBrowser.WaitForElement(expr, 4000, false);
           Element e1 = ActiveBrowser.Find.ByExpression(expr);
           HtmlControl ctrl = new HtmlControl(e1);

I hope I provided enough information and would appreciate any help!

Hello Mario,

I am sorry to hear for the problem you are experiencing.
Since this is a memory issue the best course of actions here is to have this reproduced on our side. This way we can investigate this in our debugging environment.
Is there a way you can provide us with the project so we can proceed? If you decide to do so please make sure you open  a support ticket instead of forum thread where all the information provided remains confidential.
