Yes. But the memory loss was so rapid that by the time I re-booted the system, I couldn't open Resource Monitor. I was using Speccy to track memory use. Where in the Task manager can you see memory usage by process? I can see CPU but not memory use.
At any rate, the issue seems to have been corrected. Memory is stable now (with MWB running).
in task manager under the Process tab you’ll see
Image Name|User Name|Session ID|CPU| Mem Usage
click where it says Mem Usage twice, the first time you click it it will display usage from lowest to highest, the second time will switch it from highest to lowest and show you the memhog
