To reproduce: 1. Select a range of cells 2. Do Search/Replace All The selection has been replaced by a selection of only the cells the replace was executed in. To execute multiple Search/Replace All on a block of cells, the block must repeatedly be selected. As far as I can tell, none of the settings in the search/replace box affect this. Whether cells are actually replaced affects it. It appears be be related to, but not the same as bug 81442. IMHO, a search-replace of cells should not change either the selection or settings in a dialog. These settings are user data, and shouldn't be arbitrarily changed any more than the data in cells is. Were that simply disallowed, the software couldn't do it incorrectly.
