Huge memory use when launch HeidiSQL

How do I clear "cache" of saved queries? I think I was setting a filter on a large query result when I closed HeidiSQL and when I re-open it, I think it is trying to apply the filter and thus the huge memory and cpu use as noted in Task Manager. It has been trying to load for over 20 minutes now...

Never mind, I cleared registry and re-installed and that worked.

You can also use the "Clear data tab filter" while the "Table: xyz" tab is open:
