We do not maintain a public listing of known bugs for any of our programs. For information regarding a possible bug, we recommend starting with our User Forums to see if anyone else has reported a similar issue. When we confirm a bug via the forums, we acknowledge it and generally add the bug number to the title in the forums.
A confirmed bug report in the forums will look similar to this:
[Confirmed] [#1234] Bug report title
When we have fixed a bug, we will change [Confirmed] to [Fixed] and leave the bug number in the title for future reference. You can also look at the version history section of our Download page for each of our products to see what bugs have been fixed in each update.
