Linda,
I initially meant the insurance company that covers all of the common areas of your association - the board's lack of action is potentially creating a liability for the insurance company.
However, it may not be a bad idea to find out the exclusions of your board's D&O policy - I'm almost certain that willful breach of fiduciary duty is NOT covered, and that would potentially leave the individual directors liable. Now, I am NOT a lawyer (yet)

but it would seem to me that finding out the terms of the insurance policy - both documents should be available to you as a member of the association - would be to your benefit, and I would doubt that the Board could legally prohibit you from seeing something that you pay for. This would be both policies.
I believe that this information must be available to lenders - though I don't know to what detail. And of course, especially with insurance policies, that is where the devil is found - mainly in the exclusions.
Having said that, I do not know what state you live in. I'm in CA, and there are so many HOAs here, where so many people have had problems that the state leg. has had to enact amendments to the Davis Stirling act in order to provide homeowners more protection. This includes the duty of the board to make certain documents available to homeowners. I don't know what other states have to offer as far as protection of homeowners rights.
Please also look into your state's corporations code if your HOA is incorporated. You are then considered a shareholder in the association and you have rights under the corporations code.
