Just now I performed a paste of some fifty items from the clipboard and noticed that the properties pane was updated several times while the items were added to the grid. This made me wonder whether IQ's refreshing of the properties pane had any significant influence on IQ's overall performance and whether some functions could be optimized by skipping or delaying updates to the pane? Just a thought, I realize that performance issues have been discussed and addressed here several times before. Thanks!
