extra mousedown messages

[Wouter]

Hi All,

Having had some problems caused by extra messages generated in  
certain cases, I started hunting them down.
For this I used the following recipe:

- create a mainstack and add a push button and a field with locktext  
true.
- set the script of the card or the stack to:

on mousedown
   if the optionkey is down then
     put ""
     exit to top
   end if
   put "mousedown" && the target && the millisecs  & cr after msg
end mousedown

on mousedoubledown
   put "mousedoubledown" && the target && the millisecs  & cr after msg
end mousedoubledown

- try performing a mousedubbledown and keep the mouse down
- then release the mouse button and observe what happens

Seemingly it gives the same results on Win32 and on MacOSX.
I'll give the results with a push button:

in rev 1.1:
mousedown button "New Button 1" 1178096016059
mousedoubledown button "New Button 1" 1178096016178
--> mouse released : no further messages

in rev 2.1:
mousedown button "Button 1" 1178096229057
mousedoubledown button "Button 1" 1178096229203
mousedoubledown card id 1002 1178096229208
--> mouse released : no further messages

in rev 2.5.1:
mousedown button "Button" 1178096730853
mousedoubledown button "Button" 1178096731000
mousedoubledown card id 1002 1178096731013
--> mouse released -->
mousedown button "Button" 1178096731733

in rev 2.8.1
mousedown button "Button" 1178096881969
mousedoubledown button "Button" 1178096882131
mousedoubledown card id 1002 1178096882145
--> mouse released -->
mousedown button "Button" 1178096883161

Question: is this considered normal behavior?

PS: this is not the only condition extra messages are generated.


TIA.
