Wonderful... :-/

I checked my vid settings and there are not specific applications set up to run special 3d setting cases.
My Snap settings are set to factory default.
I do know that this is NOT happening in a parallel opened version of Apr beta. (or so I thought - it is more based on the physical arrangement in the display... see below the pics).

Here is my test file, but from the sounds of it, anything out of the ordinary is only happening to me... "I saw it, it took a bite out of my boat" he says. ;-)






This strange selectivity changes with the scale at which I zoom in and out.


I took further measures to rule in/out the anti-aliasing setting in the Invidia setup.
(NVIDIA GeForce4 Ti 4800 SE)

With anti-aliasing turned completely off, selection works fine!

--you have to re-load MoI after changing--
With it set to something called 2xQ, I am NOT ABLE TO SELECT ANYTHING!
Something called "4x" is its highest setting, this is where I was currently set at.

I am able to achieve this 'selectivity' with the older version too.

By the way, it all seems to work fine when the anti-aliasing option for the Invidia card is set to "Application Controlled".
Which means that there is no card-forced anti-aliasing to the operation of MoI.

(the above pics are kinds moot now)

Thanks for the quick advice Michael... Knock on wood, I think this may be it.

I changed these settings to "default 'Quality' " when I was messing with it the other night. It changed it to "4x" anti-aliasing from "Application Controlled"

Since I can control this effect that I was experiencing by changing these setting, we must assume that this was the issue.

The other two issues with the lagging seems to have cleared up too.

:-) Whew! (for now)
