Cursor freezes, Screen spontaneously jumps to tile view

I've repaired permissions a couple times. Is your suggestion different? Re-install OS...download Mavericks again? Thx.

You should be able to reinstall it from the Recovery Partition. What is this? where do I find it? thx.

I've just done this Eric. I'll let you know in a day or 2 if it's solved the problem. Thanks.🙂

Grrrr...the problem persists.😟

Thanks Eric. My brain's a bit fried, not getting around to this immediately. Will try later today or tomorrow.

Here's the report. I've put the items which were in red on my in bold. I notice that AVG net shield is listed. I've eliminated this several times, yet it' still here...could this be a problem?

I see that my BU disk is too small. Do you know, does that mean I have to buy a new one? 500GB Seagate...or can I get an add-on for this unit? Will now continue w/ setting up new account.

I reset as you said. And logged in w/ new account, actually an old one I'd set up as a test some time ago. But I can't do anything once I'm in the new account. So I don't see how I can tell what's going on. The problem is intermittent, although just now, after the reset, it seems if anything, to be worse, that is, it started immediately after I opened these pages. Although as I continue posting this, no problem. The issue is always intermittent: can be fine for hours, then glitchy. 😕

I am wondering if this relates directly to mavericks. I only started using it sometime in the last 6-9 months, can't remember exactly. Would it help to download a fresh copy? Or maybe it's time to move on to Yosemite?? thx.

Hi Eric. I've just remembered something. I started this problem-solving on the Logitech forum, as I use their Trackman. What was rather hilarious is that from my search, I ended up on a page that was me asking the same question 2 years earlier!. I don't think the resizing windows happened at that time, but the cursor freezing was. I ended up buying a new device. And yet only a few weeks earlier I'd come across an old Trackman, had no recall why I'd need to replace it, and it seemed fine when I plugged it in. So some part of this problem seems to precede Maverick.

My one theory is that the problem is in the cord. I sit w/ a pillow on my lap, the device on the pillow, the keyboard on a pull-out shelfe at level of the pillow. I wonder if the cord has become brittle enough that it needs to be at a very specific angle in order to be reliable. I'm far more careful now, whereas I used to tilt it in the left hand, and operate w/ right. I didn't think to ask this question when I was trouble-shooting w/ Logitech. cheers, ahmo
