I've just tried 5.21 Enterprise and the last 5.22 Enterprise Beta and they both give me the 1044 Access Denied error when I click on the Object Browser or Click on the Database name to get the list of tables. This happens when connecting to my database at the webhost (I've made sure my hostname is a host that can access it via their control panel).
Works fine connecting locally to my local MySQL server.
I've sent a support ticket to the hosting company as well to see if they've changed something. About all I can do is SHOW VARIABLES and SHOW PROCESSLIST. Seems like a privalege problem on their end or SQLyog is doing something hinky now.
All the PHP scripts at the webhost work fine with the databases.
It all used to work.. but it has been awhile since I've tried connecting remotely.
Wonder if I'll have to use the HTTP tunneling business now..
