This morning, I updated World of Card Games with a change that many people won't notice. But others may see a big difference!
The site had a bug - it consumed computer resources, but did not release them when it was done with them. In technical terms, it had a "memory leak." It was only noticeable on certain computer systems. Over the last week, I was able to isolate the problem and solve it. My tests indicate that it's now gone.
I've had reports from some players who say that the site "freezes" when they're playing - it sounds very frustrating. I suspect that their problem was caused by this memory leak. I hope this new change fixes it!
If you have more problems with "freezing" - please let me know.
