What would cause MacBook Pro to lag when saving images?

I've noticed that my MacBook is very slow to select images to save when hitting the control key and clicking on the trackpad. It will go to the next image at times, indicating that it is not actually selecting the image to save, but rather advancing. If I hold the control key down for several seconds, or sometimes it even takes about 20, before clicking the trackpad, then it works.

I've checked cpu, and nothing is using over 10%. I am finding other things to be slow at times as well though. I have 4GB of memory in 2) 2GB slots. The Disk has about 400 GB of the 500 free. I can provide any other info that is needed. I don't know if this started with the Mavericks upgrade or not, but it did start at some point since upgrading. Any help for this novice would be most appreciated.

Answer this question I have this problem too

The more complete the description of your problem is (e.g. what OS you're using -there's a lot of those what Application you're using there are many, a full compete description, the text or screen shot of any error messages) the more assistance we can provide, and, the sooner we can provide it.. Are these network images, still images, import from camera images???

Thanks machead3. Any image or text I try and save off of the internet. I'm also finding that the shift key is slow to capitalize, and various other things. When I click on a song in iTunes, for example, and try to control click to get the menu to pop up or delete the song, the little icon that comes up to indicate that it's ready to be selected sort of fades in and out, leading me to believe that the item isn't staying selected while the control key is being held down. I've tried changing the tracking speed, but it has no effect on it. There have been other slowdowns since Mavericks as well, and I've read of others having these same, or similar problems. For example preview takes several seconds to open now, when it used to open instantly.

This is a software problem. As policy we do not address software issues... unless someone happens to have a ready answer.

Things that cause computer slowdown:

Boot volume with less than 10GB free (empty) space. Free up at least 10GB and do not go below that number.
Browser Cache corruption (reset Safari).
Repeated crashes scrambling the master volume directory - Boot from Repair and repair the boot volume.
Too many apps open at once... clicking the red button does not quit an application that can have more than one window open (Safari - Mail - word processing ) as opposed to calculator, iPhoto, system preferences that only allow one open window. Look at the throbbers in dock ensure you are running programs in the background
Runaway applications - kernel task has been reported as problematic on some machines converting to Mavericks.

Were I you' I would go back to the last working OS you had unless you have some "need" (new peripheral or app) that only works under Mavericks

For more help go to Apple Discussions under MacBook Pro and also under Mavericks to explore other possible cures for your problem.''

Thanks again, machead3. I tried everything you recommended to no avail. Being a novice here, I'm hesitant to roll back to Snow Leopard. I guess I might just have to learn to live with it...

Thanks again for offering your advice!

Doyle over at Apple Discussions, and through Google you can find out how to "roll back" to an earlier OS... you'll want a good complete backup of all data (not apps) and after you wipe the old drive and put back the old OS choose "restore from backup" ... do all the updates. Mavericks IMO was released really green, and, especially on many older machines (and even new ones) is problematic.
