No access to task details after a search

No access to task details after a search

Hi,

When looking for tasks by keywords with the search at the top I get a list of results. Clicking on a task title should then take me to its details in the edit section, but it does not - I get sent to the tasks list again, (on top of that, with all tasks listed whereas I normally only show open ones, but that happens whenever I return to that list.)
This is an issue for me as I often need to search tasks. Tried under both Firefox and Chrome.

Running latest Firefox and Chrome on Windows 7 64bits.
I have seen the bug does not occur on a Vista32 pc.
Thanks for your help.
