That's exactly what I experience and mentioned earlier...

I find that GUI quite helpful for the basic settings, not to have to tamper with the registry for standard tweaks and turning on and off easily. So far it is being kept up to date with the latest version of dwm.dll...

for me 2D makes the frame slightly "flashy" - don't know how to describe the effect; 3D is perfect though (except 2nd monitor being opaque)

Yeah, they have different resolutions. That they use different gfx-chips doesn't matter, though? Caption Blow would be helpful in certain settings, with high blur not so much needed... Buttons, I actually like the Win8 flat style, just not opaque... You probably mean dwm.dll? I did change settings several times and turned on and off, but... Could it be I have a wrong "syntax" with the path in the reg? I used "C:\DWM\my.png" with and without "", also tried c:\\DWM\my.png (path itself is right, that's where I put it...)

[1] I have two monitors on Win8 x64 Notebook, external via HDMI, internal uses HD3000 and external uses dedicated Nvidia GT 525M Beta 1 works perfectly on internal screen, but external screen is unchangedly opaque. If i let a window span the two monitors, it's borders are half glass half opaque. I use the GUI, 2D or 3D setting makes no difference... Any advice? [2] I tried the my.png as described, and I figured it is supposed to add glow to the buttons and window caption, but it does not work... I added "C:\DWM\my.png" as reg_sz to the resp. key; for reloading the DLL I disabled and re-enabled glass via the GUI (is that sufficient?)
