Executable only problem

[Dave]

Hi - I am simulating an underwater scene and used a great routine posted on the forum a while ago. It uses a water.dlr file to give a moving sea surface. This works fine in Vizard 3.0 but when saved as an executable file causes the programme to crash. It says Vizard launching then opens the moving graphic then closes immediately - although both winviz and the executable remain running in the task manager. Removing the line add ('water.dlr') solves the problem with the executable but of course has no sea surface. Any ideas anyone?
