Suddenly snaps are slowing down Attract Mode to a crawl

[Neil]

Everything was running so well, and then suddenly after powering up today I find Attract Mode is like a snail, every up or down I press on the games list freezes the picture for some 3~5 seconds before moving to the next game. Even the escape key takes seconds to react. After multiple reinstalls and moving my backed up files back in place, I found the problem was the snap videos. Even with a single video if I scroll over the game with the video it will act that way. Without them everything moves smoothly as always.

I run Windows 7 64bit on a newly built Groovymame pc to crt, so all components are just a few weeks old. 
Video card is an HD6450 and the processor is an i3 7350k with 8gb ram.

Games work fine when launched, nothing out of the ordinary.

There is no other software installed other than Attract Mode and Groovymame. The last thing I did was unplug the mouse from the front and plug it in the back on one of the two original plain usb ports. I have since moved it back to the front but I don't know if that is the cause.

Any help would be greatly appreciated.

Try changing your layout to "Basic" and see if you still have an issue.

I already had it in basic. So I solved the problem and it was the keyboard mouse I think. By unplugging them and plugging them elsewhere I seemed to have messed up something. I ended up unplugging the arcade stick and the audio cable as well, after plugging those back and moving snaps back a few at a time I found everything was working all fine, so I copied all the snaps back and it was all fine. However after that I unplugged the mouse/keyboard from the front to move it back to the back usb port, and it all happened again, so I repeated the same process but this time leaving the mouse/keyboard in the back, and by the time I was done everything was working fine and the devices are where they should be.

Any idea what was going on? It's a weird issue, but anyway at least it's resolved even though I couldn't understand why it happened in the first place. XD
