Connectix has released RAM Doubler 9.0.1, which corrects an incompatibility with Microsoft Office 2001 that we noted while reviewing Word 2001 in TidBITS 552. iBook owners who use the Preserve Memory Contents on Sleep option need to disable it with the update, however, or else the iBook will crash when put to sleep. Also, RAM Doubler’s memory setting is automatically reset to Double after applying the update. The free patch applies to owners of RAM Doubler 9, but owners of full versions of RAM Doubler 8 will be pleased to note that the free patch also upgrades their software to 9.0.1. (See "Connectix Releases Free RAM Doubler 9 Update" in TidBITS 514.) The update is a 354K download.
