Hello,

What version of OS X are you using? Under 10.3 (Panther), go into System Preferences and into the Dock control panel. Do you have magnificaton turned on? If you have the size of the icons LARGE, and Magnification to MAX, they won't get much larger.

Also, when it highlights over a menu, what menu do you refer to? A screenshot may be useful.

I am having exactly the same issue. I have a 24" iMac Intel with 10.4.8 and all current updates installed. The Dock is setup to Zoom b ut does not. On the top menu, I have two symptoms. 1) When I hover over ANY Menu item, it does not appear until I click on it. If I then move the Mouse over another Menu item, it does not appear. When I click on it, the menu appears momentarily, then disappears again until I click on it specifically. 2) Any Menu Item that is expandable (with a > arros next to it) does not expand when I hover over it. If I click on it, the entire menu disappears. This makes using ANY App near impossible. I entered a ticket with Apple support and they had me do the following in order:
A) Disk repair - did not fix the issue;
B) Archive and Install - did not fix the issue;
C) Install then import User Accounts and Applications from my full backup firewire drive. This also did not solve the issue, either before or after I ran Update (my disks are 10.4.7, the update is for 10.4.8). The problem presists in both my User account and my Admin account. I am not at home at the moment, but when I get home I will attach some screenshots.

Anyone have any ideas?

Thanks,

Hello. My system just started experiencing the same problems as you have outlined in this thread (magnification and mouseovers not working). Were you able to find any way to fix the problem. I can't seem to find any other references to this anywhere.

Hi

What fixed this problem (for me) was merely disconnecting the reciever of the mouse (a Logitech MX Laser <some-number>) and connecting it again. Oddly enough it wasn't sufficient to disconnect and reconnect the USB hub the reciever was connected to (as I initially tried out of pure laziness). I hope this is of assistance to someone :-)

Happy hacking :-)

Thanks for that, unplugging my logitech laser mouse fixed the exact same issue I was having. Thought I was going mad when I couldn't find a preference to turn off this 'feature!'

sorry to post in an old thread.

i just had this problem as well.

if you find after disconnecting the receiver, it still doesn't work. try disconnect all USB devices and plug them back in.

this worked for me.

hopes this helps..

Wow, that was simple!

I too felt the same level of frustration in trying to describe the problem!


Thanks,

Rocky

Years later and the problem still exists...I just spent a couple of hours trying to figure it out until I found this post...thanks!
