Has anyone else noticed memory usage climbing while using OG? When I opened the work file, memory usage was around 450 MB. After working for half an hour - and not doing anything really complicated - usage was over 1.1 GB. I closed the file (down to 250 MB) and reopened (about 435 MB) and after sitting idle for a couple minutes and just being in front on that desktop, memory usage had climbed again (to over 540 MB).
