If I leave my laptop on few a few hours, when I come back it's un-usable without rebooting because the memory usage remains at 90%, with several inactive minirosetta processes using a large chunk of it. I have unchecked "Leave applications in memory while suspended" so I would have expected the memory to be freed when I start working on the computer.
In the PTP desktop app on my Windows 7 laptop I've set preferences for memory usage under "Disk and memory usage" to 20% when computer is in use, and 60% when computer is idle. My projects are rosetta@home, Poem@Home, climateprediction.net and malariacontrol.net.
Is this the expected behavior or should the processes release the memory when idle?
Thanks!

Hi Hugh,
The "Leave applicaiton in memory" unchecked means that if a task is not activly being processed it would be removed from memory. If checked if your computer is processing tasks that are longer or switch often they are put in memory and can resume without reloading all over again. Some older apps would restart the computation from the beginning if no "checkpointing" was included by the developer and was a reason why this option was included. The performance loss is marginal with most projects.
If I understand your post the apps not reducing to max 20% memory use is not the desired function. The apps should reduce the memory used when you return if you unchecked "Leave applicaitons in memory". If you total all applications running they should not be using more than 20% of the memory on your computer when you return. Any non active tasks should not be in memory based on your settings.
Are you only seeing the Rosetta tasks stuck in memory? Are these settings set on the local machine or online? Any settings made locally override online settings. Clicking sync with account manager (PTP, GridRepublic, etc) under the tools menu (advanced menu) would ensure the online settings are used. Is the Windows 7 machine a 32 or 64bit machine? (see under control panel > system and maintenance > System - windows version)
I recieved a few reports of rosetta tasks not leaving memory from some other Windows users and we are looking further into the issue. Try disabling rosetta for the time and see if apps not leaving memory continues with any other projects. Disabling rosetta is the current work around for the rosetta app not leaving memory.
