When clicking at of the tabs (All, Work Log, History,...) or when clicking the arrow for changing the sort order I will see only a string "find_link" on the left hand side under "Activity" and instead of entries there appears an "Export" and "Tools" menue. But when clicking on that Jira will kick me out of the issue back into my issue search list.
Uploading a screenshot (23 kb) will not work here... 
What's wrong? Hope someone may help.
Thanks, Oliver
