In Find Tracks when I try to select More Filters when i click on check box of desired filter it check and unchecks it self, when I click on textual part it works ok.
No biggie just wanted to report it if you did not know.

It's an "issue" in Firefox. Still haven't fixed it .
Thanks for reminding me of its existence, though .

Checked, and this is still an issue.

This is fixed.
