Minimize all SeaMonkey windows. 5. Watch memory usage again. Actual Results: The physical memory usage of SeaMonkey is the same as before minimizing all windows.

WFM with SeaMonkey 1.0b Windows release on Win2k. Make sure you differ between conventional and virtual memory, as only conventional memory usage will drop!

I still have the problem with latest SeaMonkey 1.0b branch nightlies. Conventional memory only drops after minimizing the console window (-console starting option), indepentently of the status of the other windows. But without -console there's no way to have any change in conventional memory. Perhaps it's some issue with Windows XP Home SP2, since Karsten isn't seeing it for Win2k?
