Are you only talking about the trackpad? A Bluetooth mouse? Sometimes RF interfeerance from wifi or other bluetooth devices can interrupt the mouse signal.
Other software running in the background?
Thanks for replying Rick!
I'm refering to my mouse pad on my laptop. However I also have a wacom pen tablet that I use as well and it acts as a mouse. Usually that one works over the built in mouse pad of my laptop, but most times neither work. And the tablet is just plugged in with a usb cable.
I try not to run too many softwares at once but if I do, it's usually After Effects and...Google Chrome. Maybe Photoshop - in case I need to make up some images to import into After Effects, but most of the time it's After Effects and Google Chrome only.
I had After Effects on my old computer (It was a dell inspiron 1500 I believe...I don't remember but After Effects was barely able to even run on it!) I had my Toshiba (I mentioned the specs in the first post) for about a year and only reinstalled After Effects about half way through the year of 2013. I noticed it happened a copule of times but didn't think much of it. There was a time perdio where I didn't need After Effects for a while (like a couple of monthes) but sometime...in Dec. I think, I used After Effects and I noticed it started to happen again.
It's really paculiar because it only happens in After Effects, and I only started using Premiere this week, and I noticed it happend there too. That's why I decided to post in the forum. It's really werid!
There is probably a driver conflict somewhere. Make sure everything is up to date. Make sure you don't have any 3rd party mouse or track pad drivers installed. Wacom tablets have been notorious with AE for quite a while and you must make sure that you have the proper drivers installed for AE to work. I work on a Mac mostly and seldom use a Wacom tablet so I'm not much help on that end, but I'm sure that someone somewhere has the Wacom driver problem worked out. I'd check their user forums.
