Issue with too many attributes in backend

Hi there,
I’m looking forward to use your swatches plugin.
In all tests in my test environment all works very well!
But after installing it in my live environment with many product variations and so attributes your plugin has an issue in the admin backend settings screen.
When trying to view the “Swatches Settings for Global Attributes” the screen gets frozen after about displaying 50 (from about 1000 values) of the first attribut!
Hope you can help me with that and get a quick fix!
Thx …
