My PC is running on Windows 7. Normally a drop down list would appear as to my recent documents for an application (excel, word, powerpoint) when i hover or point the said application on the panel list. Currently i can view all the drop down list for all applications except excel. I have not modified nor customized my settings. I had several documents pinned on the list for excel and i find it convenient to open them on the start menu rather than looking at the folders. How can i fix this? Thanks.
