Since around beta 4.9.1, every search seems to produce a handful of undownloadable results. They show stars or torn paper, and if you select them and hit "download" they don't change to folders, don't actually start downloading or anything, and no prompt pops up either (such as "overwrite this file?").

Also, since installing beta 4.9.4 I'm having odd problems previewing image files I've downloaded. The Windows previewer keeps showing "drawing failed" or getting hung "generating preview..." or "drawing image..." -- the images look fine when opened in a paint program so it's the previewer that's malfunctioning rather than the files being corrupt. (Besides, I have Lime set to automatically abort corrupted downloads.) When I switched to this Web browser window to report these problems, the browser acted funny too! The display only partly redrew, and buttons were missing from the toolbar and the Google search box was missing. This is with a recent version of Firefox. No error messages, just abnormal behavior. Eventually it redrew itself properly and I wrote this.
