McAfee have been in contact with me this morning and they have produced a new
dat which is supposed to fix the reported problems when using Toad 10.6.0,
10.6.1 and 11.0 beta.
Once they have sent it to me, I’ll let you know how to obtain a copy.
McAfee will also be updating their own Knowledge Base article (hopefully
sometime today) so you might be able to download it from there.
