How are you copying the files? Toolbar? Drag & drop? Copy & paste?
Where are they being copied to and from? Network drives or special system folders at either end?
It's not just that they are copied so quickly that the progress dialog doesn't appear, is it? By default the dialog only appears for operations which take more than a second or so. Can be changed via Preferences - File Operations - Progress Indicators.
What kind of folders?
Please follow the debug steps in the FAQ, Changes to folders are not being detected, and post the results here.
(Or in a private message or to GPSoftware support if you don't want everyone else to see the filenames/paths.)
