Connectix Corporation released a free upgrade to its popular memory optimization tool RAM Doubler this week, tweaking the utility's speed and offering greater stability under some circumstances. This release comes on the heels of the RAM Doubler 8 upgrade, free to registered users of the software (see "Free Ram Doubler 8 Update" in TidBITS 439). Version 8.01 resolves problems using the RAM Doubler control panel with older versions of the Finder in low-memory situations, speeds up application launches on PowerPC-based machines with large amounts of memory, and fixes a rare problem where a write-protection fault by other applications could freeze the computer. The updater is a 390K download available from the Connectix Web site.
