Hi there’s not much information to fully understand what’s actually going on.
What OS are you using? (Windows or Mac)
What version of OS?
What copy of World of Warcraft are you experiencing issues with? (Retail, Classic, TBC)
Can you please provide more detailed description of the issues, i.e provide some steps so that we can try to replicate it so that we can work on fixing this or to provide you with a solution. I would like to help you.
I agree, this is a great addon, armed with loads of great features including awesome guides.
