When I come back in the next day if I click the edit page icon in the right margin it opens the page for editing.
If I click the "edit" button within the page itself to edit just the last day so I can add the next day's title it drops me back to my home page, from where i have to click through back to the work log page again.
There are two standard edit buttons:
1) in the right hand margin is the pencil icon
2) at the bottom of each editable section is a rectangular edit button which is marked 'edit'.
The pencil icon opens the entire page for editing and the section button opens the section above it. If this is not what you are getting, there is some kind of error occurring, presumably javascript. Then there are a number of checks you can make. First, does it happen in every browser you have installed on your desktop? Secondly, disable all plugins. Does it still happen? If not, enable your plugins one at a time until you find the culprit. The only puzzle here is that it happens only after you've run some external process, or is that not correct?
