"Save as" message "not responding"

[WB13646 0]

First time I perform Save as for Notepad file, Excel 2007 file or Word 2007 file after running CCleaner v5.52.6967 (64-bit) it takes several seconds for dialog box to open to select location and name of file.  While waiting for dialog box, message at top of Notepad/Excel/Word windows displays "(not responding)". Second and successive "Save as" work perfectly....until I perform another run of CCleaner.  Any suggestions????
