Yes - the IDE in 8 is based around a much more accurate monitoring 
system for changes to the object tree. It isn't perfect, and does need 
some improvement (with regards working correctly under lock messages) 
but generally it is 'better' than before.

Ideally all the IDE updates should be pushed off until 'there is 
sufficient time to process them' - i.e. we want to do the equivalent of:

   send "updateIDEPalettes" to me when idle

However, it is going to take a significant amount of reworking of the 
engine's core event loop (on 5 different platforms) in order to support 
'when idle' (we know this as Peter attempted to do this a few months ago 
but it turned out to be a complete rats nest). The best we can do at the 
moment is throttle the update messages so that they don't 'overload' 
pending messages.

That is potentially the cause of the % slow down you see when doing a 
great many LiveCode script object related operations (as the DataGrid 
does) in the IDE.

Warmest Regards,

Mark.
