Just updated to 10.0.0 (Release) and my macros that include /click actionbuttonX lines in macros no longer work. I reverted to 9.3.5 (Release) and functionality returned.

How are you triggering the macro? Does it happen to be via a shift key combo?

Likely relates to the lua error Couldn't open Dominos\Bindings.xml. Generates twice on every character login.

I have a /click actionbutton1 on nearly all my shots as a hunter to handle my pet actions. So I am triggering the macro through hotkeys, some without a modifier (1-4) some using shift, alt, or ctrl. It failed in all scenarios.

The current workaround for this is to remind your keys.

This may be resolved in the latest release (10.0.1)
