[TRNSYS-users] Strange behaviour type 50b

[David BRADLEY]

Benjamin,
   If Alastair's suggestion didn't do the trick then I'd guess that it 
isn't possible to know what the error might be without looking at the 
project. Please send the Studio project file(s) to your distributor's 
tech support hotline.
regards,
  David
