drill through definitions

[skunkyno]

hi guys
I have a problem I can not solve.
I need to modify a drill-through definitions, but if I try to select property settings, nothing happens.
do not display error messages but it just is not allowed to change any of the properties.
I use the user who owns the administrator profile and my browser is Internet Explorer 9.
Thank you for any suggestions

probably the problem was caused by an automatic update from Microsoft, but I can not identify which one.
can someone help me to locate it?

Just an idea off the top of my head, but are there write permissions on the package the drill-through is contained in?

no.
seems to be a problem with some local PCs and not at all.
with some pc modifying the definitions work correctly, on others not.
is not a permissions issue.

it is not even a problem with the properties of internet explorer.

seems to have found the problem.
is an automatic update of microsoft that generated this error.
we are trying to see which update has created the problem.

when I checked what update is, I try to post the code in case anyone else had the same problem.
