Hi Peter,
In my doc (dictionnary), I read :

Here, in the docs of Rev 2.8.1 (Enterprise) it is :

The blendLevel of an object is an integer between zero and 100.
By default, the blendLevel property of newly created objects is set  
to 0.

If an object's blendLevel is zero, the object is fully opaque. If the  
blendLevel is 100, the object is fully transparent. Values between  
zero and 100 indicate levels of partial translucency.

The following handler (in the script of the splash stack)  works here :

ON openStack
   set the blendlevel of stack "SpashStack" to "0"
   show stack "SpashStack"
   wait 2 sec
   REPEAT while the blendlevel of stack "SpashStack" < 100
     set the blendlevel of stack "SpashStack" to (the blendlevel of  
stack "SpashStack" + 1)
     wait FOR 1 ticks
   END repeat
  open stack "mainStack"
END openStack
