I suggest that you read this FAQ article:

Another reason may be if your test code uses long timeout to wait for the object and object does not appear for a long time.
var obj = page.WaitAliasChild('TableWithAlotOfAjaxDataOverSlowConnection', 60000);
The above line waits for the table to appear within 1 minute. If you click Pause while the code is waiting for the table, the code will not be paused until either the table is found or timeout elapses.
To workaround the above inconvenience, you may replace single .WaitXXX() with a loop and smaller wait.
var iStopTime = Win32API.GetTickCount() + iTimeout;
// Wait for the element to appear
obj = page.WaitAliasChild('TableWithAlotOfAjaxDataOverSlowConnection', 500);
while ((!obj.Exists) && (Win32API.GetTickCount() < iStopTime))
