I think the problem is that you're using a data target with the FXText 
widget, which is probably not especially optimized for that. The data 
target is continuously replacing the text buffer with the current 
contents of @log, which causes all of the metrics for FXText to be 
recalculated.

Don't know, other than searching the foxgui-users mailing list archives.
