But there is a difference depending on the OS.
Under Win Xp 32 bit while copying - there is now displayed one inactive cursor in both panels. The cursor in the source panel is only shown if one or more files/dirs are selected though.
Under win 7 x64 in both 32 and 64bit versions of TC there is only displayed an inactive cursor in the target panel.
IMHO there should be shown an inactive cursor in both panels whenever internal ANY dialog is in the front (just as when a third party program is in focus) - this is almost the case under Win XP 32bit except that a file/dir has to be selected when copying or moving and there is no inactive cursor when showing the delete dialog.
Under Win 7 x64 I have so far only seen an inactive cursor in both panels when the CbC tool, Lister or the Properties dialog is opened.
