[DUG] Shellexecute issues in Delphi - call hangs until the program it starts finishes.

[Phil Scadden]

Having some issues with shellexecute in a program.

Basic code is
If (blah) then
  Shellexecute(application.handle,'open', program1,params,nil,SW_SHOWNORMAL)
else
  Shellexecute(application.handle,'open', file1,nil,nil,SW_SHOWNORMAL);

file1 is associated with a program, (not written by me) and works find - 
it opens the correct program and continues fine.

program1 however is written by me and what happens that program1 opens 
just fine but the caller hangs on the shellexecute until program1 
terminates. Eventually the operating system just kills the caller as a 
hung program.

Obviously shellexecute is waiting for something???  What is program1 
failing to do??
