Search history

I was using Find Toolbar to do searches and was using the history pulldown to switch between various searches and replaces. While trying to find out a way to do a Replace without jumping to the next find on a particular piece of code (I had been clicking the Replace Next button), I clicked the search menu and selected Replace which opened the find/replace window. After realizing this is not what I wanted, I closed the find/replace window and discovered my history of Finds and Replaces in the Find Toolbar had been erased.

Please have it NOT erase the history.
