Search term stuck in search box

[MrZZY]

I'm using an older version of Mantis and a search that I made (not one that I saved) keeps appearing in the search box and being applied as the search filter every time I switch to a new project. I've tried clearing cookies and it hasn't helped. Anyone any idea why this is happening?

Anyone know how to clear this persistent search? I've cleared cookies. I've tried a different browser. The search must be being reloaded from somewhere in the database!
