The following problem was reported on CIX&nbsp;(UK)&nbsp;by someone who is evaluating FB.&nbsp; I&nbsp;have reproduced it in build 2004 here, but the failure is also reported not to happen on XP.&nbsp; Reduced to its simplest form...

On Windows 7, 64-bit, create a new project and one 'Wait for Window or Control' action.&nbsp; On the action dialog, just enter a target process that is known not to exist.&nbsp; Run the project.&nbsp; Press the red button 'terminate action and stop build'.&nbsp; FB&nbsp;crashes.
