Under normal conditions, I use the modal login dialogue. My site includes some style switching from the pagestyle and textsize modules and I'd like, when the style has been switched, to disable the modal login. The dialogue is indistinct and I've not been able to style it appropriately. Better for accessibility, I'd say, to disable it once a style has been switched.

I can easily create a test to see if the style has been swicthed, but how do I disable the modal dialogue?

Thanks for reading!
