I have a weird bug with Mail.app since DP7, which is difficult to explain (at least for a non-native english speaker ). When I open an email in Mail.app, the windows of the mail is closer to the dock than for the previous email I opened, and is getting smaller and smaller. Its like this for each email I open. Thus, after like 10 emails, the windows is so small that its nearly unusable (see the screenshot below). I have to manually move and resize the windows when its getting too annoying. I just sent a bug report to Apple. Anyone else is having this problem?
