Hello All,Having a problem with my 737NGX where if I do anything related to windowed mode (alt-enter keypress, or if I bring up a window such as the Squawkbox window), I go to black screen and eventually, if indeed I get something back, the screen looks VERY strange with bits and pieces of scenery missing, strange looking clouds, black sky, etc. I have many other aircraft add-ons, and this is the only one effected. I am running Windows 7 64-bit, NVidia GTX 560 ti with the 285.66b drivers, 8 gb ram. I also have recently, after some reasearch on the problem, added the HIGHMEM=1 line to the Graphics section of my FSX.CFG file. Any ideas? I downloaded the iFly 737ngx package last night, but honestly, it doesn't hold a candle to this bird, and I really want to get it running with Squawkbox so I can fly on-line. Thanks!Paul

Hi Paul,Do an Avsim forum search for UIAutomationCore.dll there are several post explaining what this is and how to cure your CDT.

Hi David,I found the dll and installed to the main FSX folder. After a quick flight with the NGX tonight with the Squawkbox window active and an alt-enter keypress to go into windowed mode, everything worked fine!! Thanks so much for the help, my friend!!Paul

Glad to see you are up and running! UIcore.dll was a lifesaver for me. :(
