Ultra Modern UI modifies shell var context

[alexmitev]

Hello,
I noticed the use of the Ultra Modern UI causes modification of the shell var context that I've set. Minimal reproduce program:

PHP Code:

!include UMUI.nsh

OutFile "produce.exe"

RequestExecutionLevel user

!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "English" 

Function .onInit
    SetShellVarContext all
FunctionEnd

InstType "Typical" 

Section "Core Files (required)" SectionCoreFiles
    SectionIn 1 RO

    !insertmacro UMUI_GETSHELLVARCONTEXT
    Pop $0
    MessageBox MB_OK "$0" ; displays "current"!?
SectionEnd 


I get this also with MUIEx.nsh
With MUIEx.nsh I also get a fantastic "Threat blocked" fatal notification from Avast (I cannot attach the png screenshot from Avast here)
