Anomaly comment code Toad 11

hi to all

I have a strange problem in Toad version 11 with the Comment code.
I’m not able to select a single word of the comment.
I’m not able to position the cursor type editor with the mouse at the beginning of word and select the entire word.
If I try to select the word Toad selects the entire line of the comment.
For example, Suppose we have the following comment:

– comment1 comment2 comment3 comment4 comment5
– comment6 comment7 comment8 comment9 comment10
– comment11 comment12 comment13 comment14 comment15

if I try to select the “comment8” word the result is that the entire line is selected “comment6 comment7 comment8 comment9 comment10”.

Practically, I’m not able to position the cursor type editor with the mouse at the beginning of the any word wrapped in a comment!!

Can anyone tell me why?

Thanks.
