a few bugs i've noticed since 373:

1. in the media viewer, if you click on a link on the top-right of the viewer, it will always bypass what browser you've set in the hydrus options and it will use the default browser on your system. (this doesn't happen when launching the original url from either a shortcut or the right-click thumbnail menu, though.)
2. on windows, if you open up the tag editor from the media viewer, you can minimize and maximize the tag editor that pops up. not sure if that's intentional.
3. as of the latest version (v376), if you have the ui style set to 'fusion', closing the options menu (when hitting either apply or cancel, doesn't matter) will make the client lag out for a second or two. i'm assuming this is because of the new theming options you've added.
4. if you have the ui style set to 'fusion', sometimes if you right click on a tag in the selection tags pane, it will automatically select the first option in that menu without asking if you let go of the mouse button too early
5. ever since 373, scrolling through thumbnails has been SLIGHTLY slower than on the wx builds. not sure if this is fixable but i thought i'd point it out
6. the 'collapse all notifications' arrow button is wider than it was in the wx builds. again, not sure if intentional

i think there are a couple more i forgot to put here but overall i am happy with the recent versions so far. if you can fix up these issues that would be really good. thanks dev!
