When I try that it gives me "Error has occurred: ERRNO #288.289", exactly the same as from the commandline with WED. I have tried
Code:
WINDOW WINSTART
{
}

as the content of the file main.wdl and the command line was
Code:
C:\Users\My User Name\Desktop\test>"D:\Program Files (x86)\GStudio8\wdfc" -smain.wdl -omain.wdf -t -ex -run



Always learn from history, to be sure you make the same mistakes again...
