Favorites folders won't expand in IE drop-down menu
I hope this is the right forum to post this question. I'm having trouble with internet explorer on my wife's latitude d600 with windows xp professional (with SP2) and the latest version of explorer. At seemingly random times, when I open up internet explorer and click on the favorites drop-down menu, I can see sub folders in the favorites menu except they don't have the little drop-down triangle to the right of the sub folders, so the only way to see the favorites links inside the sub folders is to actually click on the sub folder in the favorites drop-down menu, which then causes explorer to open up a separate window with the links contained in the subfolder. However, sometimes internet explorer will work correctly and will allow me to highlight the subfolder which then automatically opens a drop-down list of the links in the subfolder. I can't figure out what's going on. Any sugestions?
Thanks in advance.
