Blink dude!
I think you got it!
I found my biggest problem... It's my PC...
I switched to my Dell XPS Laptop and the nasty problem went away...
Ok then... the main thing I think you need to do is:
1.) Revise all skins and bitmaps to be "power of 2" ie 32x32 or 32x64 or 256x512 or 512x512, Get it? always use any of these numbers...
16,32,64,128,256,512,1024... or say 128+256 etc...
That will help a lot! Now and in the future!
2.) I suggest you lighten it up a bit... I think people would like to see a little bit better without the flashlight...
Ok then...
Glad I could help!
