Well, that was a heated discussion back there.. anyway it doesn't take a genius to understand that DWMglass.dll somehow screws up system security. Hell, one of the versions of aero glass requires secure boot to be disabled??! WTH. No thanks. I'll stick around with ugly flat windows borders while I wait for someone to crack Mr. Developer's tool or create a tool of his own, free with no nags. Your tool is fantastic, Mr. Developer. Too bad you let yourself be taken by greed. cheers.
