Nullsoft Scriptable Install System

NSIS 2.45

When creating an installer using MUI2 and using a custom page through
nsDialogs the first label control on the first custom page will go
invisible after a few seconds. It can happen after a random amount of time,
but we can sometimes trigger it by moving our mouse from off the installer
onto the custom page area. It is then that the label control disappears.

The only solution that we found to this, and it solves it perfectly, was to
edit the nsDialogs.nsh file at line 189 and change it from "!define
__NSD_Label_EXSTYLE ${WS_EX_TRANSPARENT}" to "!define __NSD_Label_EXSTYLE
0". This suggestion came from one of out programmers who had a similar
problem with a Windows app he was writing and a label control was
disappearing. When he removed the extended style the problem went away.
