LSH installed but cannot run widescreen

[K-61]

I have successfully installed LSH2015 and I can get it to run on my widescreen notebook, but it has the ends "blacked" and is displaying as if on non-widescreen monitor. Everything within the display looks normal.

My graphics driver is up to date and I have performed the suggested configuration of the graphics chipset [AMD Radeon] and it is the same whether set at "maintain aspect ratio" [the default setting] or changing it to "scale image to full panel size" as suggested in the installation manual. I have activated, in turn, each widescreen mod via the built-in JSGME but every time I try to start the game with such a mod, I get this message:

"The program can't start because d3dx9_42.dll is missing from your computer. Try reinstalling the program to fix this problem." My 17" widescreen display is set at 1920 x 1080.

When I deactivate the widescreen mods, the game starts and runs.

This is very strange, but at least I can get the game to play, but without native widescreen display. I am somewhat disappointed, but on the other hand I can get the game to run, which is the main thing.

One general question about LSH: I notice within the HSIE options there are a couple of mods for NYGM [crash dive] and GWX [night vision fix.] Since I do not have either of these mods installed, I have not activated these two features, but have added all of the others.

Does this mean that LSH can be installed on top of GWX or another super mod?
