Trying to Use Ruler in Enhancement Suite Causes Multiple Bugs

I'm on an updated version of Firefox with all add-ons disabled except the VTT Enhancement Suite. I can play around with pretty much everything just fine until I simply click on the ruler. Once I do, I can't do animations, move my tokens (they do a bizarre select thing), draw shapes, etc. I can roll my 3-D dice, but that's about it. Refreshing brings everything back. If I disable VTTES, I can use the ruler and all other functions just fine. Anyone else having this issue?

If VTTES is giving problems, be aware that they are a third party product, and not supported by Roll20. It would probably be more productive to report on their site. I believe they have a discord for feedback and bug reporting.

Cheers, appreciate the reply and info. Roll20 may be interested in hearing about it, though. Our group is looking for other options as this isn't the only issue we have with VTTES.
