This is a big problem when I'm in the buy phase and try to view the text of a card only to discover I just bought it. And then the game moves on to my opponents turn making it much more annoying to ask for an undo.
It only happens rarely, maybe 2% of the time.
I'm on a mac with a standard 3-button mouse, using the Firefox browser. None of my extensions look like they would be causing this. I never have this right click problem in any other programs, so I don't think it's a hardware or OS issue.
Also, sometimes when I right click a card, it fails to display the big version of the card, but it does lock up the rest of the interface until I click somewhere, as though it thought it was in the card display mode.
I played on dominion.games for years, and it never happened. I stopped for a year or so, and recently restarted, and that's when this issue started. The only change I made to my setup over the past year was switching from Chrome to Firefox. I have not tried switching back to Chrome.
I can work around it by not right-clicking when there's a chance that a left click might do something. But it's hard to remember to do that.
Thanks for all your hard work!
