Great app but can

I want to echo everyones comments here and say that I absolutely love the fact that I dont have to go online to add/modify cards, etc., this app is great! But I do have a bug to report: for some reason I cant attach files from my desktop. When I click on the Attach File button for a card and when I click Computer I expect to get a browse folder directing me to my files but nothing happes. Alse there is a tip at the bottom of the Attach File sub-page that suggests that I can drag and drop files from by Desktop but that is not possible since as soon as I click anywhere else other than the Trello page from the menu bar, the app page goes away and I cant darg and drop anything into the card page.
