Context is ignored when deleting activity from activities dashlet, and Delete action link doesn't work in full-screen mode

Several problems with Activities dashlet (CiviCRM Home):

1. If you enable the Activities dashlet, and then delete an activity from there, the link carries the correct context=dashlet. However, after deleting the activity you SHOULD be redirected back to Home Dashboard, but this is not working (you wind up on Activities tab of logged in user's contact records).

2. In FULL SCREEN mode WITH CiviCase enabled, the "Delete" activity link in the "more" pop-up menu does not work at all (clicking it doesn't do anything). File on Case does work and Delete works when NOT in full screen mode.

3. When I used this dashlet on 3.4 demo today, the full screen mode was not loading properly. The dialog resize wasn't working and the css / jscript didn't seem to be loading properly. This is NOT happening on my localhost and I have no idea why it's happening on demo today ???? I've attached 2 screenshots.
