Yes, VMware's desktop virtualization products are not high on the list of "easy to report problems on".
It's not that you can't report bugs after 30 days. It's not free to do so, which is a real shame. If you have a paid license for Fusion and you're beyond the 30 days complimentary support "grace period", you can purchase the per-incident support voucher through VMware's online store. You can use that voucher to open an official support incident on Customer Connect.
It's not a perfect system, you do have to pay for the privilege which is not really ideal and it's not very cheap, but it does allow you to make sure something that's critical to you gets into the hands of VMware tech support and development.
