selection tool in MED and WED editors has a problem.
it's causing screen distortions.

whenever I want to use selection tool, either in 2D or 3D view, screen goes white and a corrupted image occurs. and when I release mouse button it returns back to normal.

please look at this image:

my operating system is Vista Home Premium 32 bit
I have Dual NVIDIA GeForce 8700M GT's (in SLI Mode)
(drivers are up to date)

here is my device setup window

I tried almost every possible combination in device setup
but I couldn't get rid of this Selection tool bug.


Preferences Window
I believe all of these are related to GXL selection.
I can not use DX9 or DX8 modes.

but, if I select gxl2bas32 then selection tool works normally.

please look at here:

using gxl2bas32 is not a wise desicion
and I don't want to use it (I have dual GeForce 8700M GTs)


please tell me what to do.

disable vista aero, this happens on some other 3d tools too(with aero).

somewhere i read in connection with such things in c4d, it may help to turn off the window compositor (vista's built-in window transparency and shadow effects) for this application.

Thank you,

it helped to get rid of selection tool distortion.
but still borders of the selection tool "blinks" when I move it.
is it normal ?
(it looks like a kind of screen refreshing problem now)
(I'm going to check the settings for that)

and after disabling the Aero feture, I have realised that when I minimize or maximize any window, window movement is a little bit "chunky" now.

maybe this Aero addition was made for this aesthetic resons.
but I don't care that. I only want to use my new software.

Hopefully I have never had this problem before, especially while I was using 3ds Max and Unreal III Level Editor where my major projects are held in.

thanks for your help.

The reason of the problem is that Vista Aero is not compatible to DirectX operations that require reading from a surface, for instance inverting a line.

Future versions of WED and MED will work around this problem by using several screen buffer layers and an offscreen buffer. Until then, the best solution is disabling Aero.

thank you,
I have disabled Aero.
