import snapshot crash...

[Eric Chatonet]

Hi David,

Sarah replied about the bug in Rev prior to 2.5.
The workaround I used at this time was to specify a globalRect  
without specifying the window ID:

   local tRect,tTopLeft,tBotRight, tGlobalRect
   -----
   put the rect of stack <stack name> into tRect
   put item 1 of tRect,item 2 of tRect into tTopLeft
   put item 3 of tRect,item 4 of tRect into tBotRight
   put globalLoc(tTopLeft),globalLoc(tBotRight) into tGlobalRect
   import snapshot from rect tGlobalRect

Best Regards from Paris,
Eric Chatonet
