You shouldn't have to keep flipping themes to make updates and 128 MB is typically sufficient.
One important question is how many other plugins do you have activated?
The more plugins you have, the more memory you use. So under most circumstances 128 MB should be enough for Gravity Forms to work fine with Thesis as well as other plugins... if you have a lot of plugins installed there are no guarantees that will be enough.
If you have no other plugins installed and it is just Gravity Forms and Thesis then something else is going on. Either there is some sort of server configuration issue OR while it appears you have 128 MB of PHP memory allocated it may not actually be allocated properly.
Let me know how many plugins you currently have activated and which ones they are and we can go from there. We may need to login to your admin and take a look.
